There are several strategies to collect unused laptops from your local community. Many of the people you know have unused laptops sitting idly and the objective is to give them an option to repurpose them and convert them into powerful educational devices. Here are some ideas to help you find and rescue idle laptops.

1. Think of 5 people who will most likely donate their used laptops.

They can be your parents, your co-workers, your relatives, your class-mates or your friends. If you are a student or a teacher in a school, you can write a letter to the students parents asking for unused laptops. Many parents work for companies that have unused laptops.

2. Pitch potential donors with the 3 favorite things you like about Labdoo.

When talking with potential laptop donors, tell them about the Labdoo story. Tell them for instance about the notions of using collaboration to spread education around the world and without incurring any economic or environmental cost. You can get some ideas from the Labdoo Value, Philosophy and Principles.

3. Be proactive!

Contact the potential donors, in person or by e-mail. Describe the benefits that each player with the Labdoo platform receives. Here are some examples of benefits:

A benefit to the donor: They are basically helping themselves clear out old things and making more space. A benefit to the community: The carbon footprint produced by a laptop is equivalent to 2 trees! (or 1500 liters of water, or 270 soda cans). Recycling laptops properly helps keep our environment green. A benefit to the children who receive the laptops: The repurposed laptops are powerful tools to help underprivileged children receive an education. Once the donated laptop arrives at its destination, the donor will be able to follow the link assigned to the laptop he/she donated and see pictures of those children using the laptops.

Additional Tips. 1. Understand that what you are doing is creating a positive impact. A change in perspective can change your whole approach! 2. If you are too shy to ask face-to-face, hand written letters or emails are good alternatives. 3. Use your social networking skills and tools to bring awareness. Write a post on your favorite social networks (Facebook, Twitter, Google Plus, etc.) letting people know about your laptop collecting activities. 4. Don’t let the idea of rejection stop you. It happens to everyone, and it’s part of the learning process. The cause you are promoting is your best ally. 5. Leave friendly reminders to the people who promised you a laptop. Many donors need frequent reminders that they should take proper action on their idle laptops when they still hold value. 6. You can be creative and come up with your own laptop collection strategy. Tagging a Laptop with a Labdoo ID Number

Each dootronic contributed to the Labdoo platform needs to be tagged and labeled with its unique Labdoo Indentifier (ID) to ensure that donors can track their donation all the way to the final destination school and/or the recycling factory.

The following steps describe the process of tagging a Labdoo laptop.

1. Login to Labdoo.org by clicking on the "My account" => "Log in" link located on the top right corner of www.labdoo.org. (If you don't have a Labdoo account yet, create one by going to "My account" => "Create a new account".) 2. On the top pull-down menu, select "Dootronics" -> "Tag it!" 3. Fill in the information about your dootronic (Make sure you fill all the fields marked with a "*") 4. If the donor desires so, it's very important to add the donor's email address to ensure that he/she can receive email updates about the status of the dootronic. Here's how: - Under Create Dootronic, select the second tab "Additional Information". - Scroll down to the field 'Additional notification emails'. - Fill in the donor's email address in this field. 5. Under "Additional notes", add the laptop condition. 6. Click "Save" once you are done. A unique Labdoo ID number will be assigned to the laptop. 7. On the new page after clicking 'save', click on "Print tags" to print the "Labdoo ID" labels. (Alternatively, you can manually write the Labdoo ID number on the preprint blank label sheets that you will find in this link.) 8. Tape the labels to (1) the laptop, (2) its power adapter, and all (3) the parts which come with the laptop. Ensure the taping is resistant so that the label does not get detached from the laptop.

Below is an example of a laptop tagging page.

Tags: tagging labdoo id How To Sanitize a Laptop

The process of sanitizing a laptop involves three aspects:

1. Physically cleaning the laptop's appearance. 2. Deleting the laptop's previous information. 3. Installing the educational software (operating system and educational applications).

Labdoo provides two laptop sanitation manuals: a Fast Restoration Method and a Step by Step Installation Method.

The Fast Restoration Method is the fastest method to install the operating system and the educational content on a laptop.

The Step by Step Installation Method is very useful if you are new to the project and want to see exactly what a Labdoo prepared laptop contains. This method guides you on how to:

1. Delete the previous content of the laptop. 2. Install the basic linux operating system. 3. Install the basic software (ofimatic applications, linux software). 4. Install additional educational content (RACHEL content, wikipedia for schools) 5. Install more additional educational content (XOWA offline Wikipedias)

This process requires more time but is recommended if you want to learn and to see exactly what contents are installed, while the Fast Restoration Method performs all these steps automatically.

If you are new to the Labdoo Project, you can follow the Step by Step Installation Method. If you have more experience with the process or need to deal with a large number of laptops, we recommend you to use the Fast Restoration Method. Alternatively if you don't have the time to sanitize your own computer, you can always bring it to your closest hub and have labdooers there sanitize it for you (click on the menu option ‘Hubs’ located at the top of the Labdoo website and then on ‘View’ to go to the list of Labdoo hubs).

If you have problems or want assistance on how to perform the laptop preparation, ask for help on the Labdoo Global Support wall and somebody from the core team will be happy to assist you.

The basic educational software package installed in every Labdoo laptop is called Edubuntu. Edubuntu is a free software platform that includes educational applications covering many areas of science, from pre-school level to high-school level and available in more than 130 languages. You can learn more about Edubuntu directly from https://www.edubuntu.org/. In addition to the Edubuntu platform, laptops can optionally be preloaded with additional educational content such as an offline version of Wikipedia and many other powerful Open Educational Resources (OER) such as Rachel, Xowa, UNESCO content, Khan Academy, etc.

The simple sanitation guide helps you to install the basic Edubuntu platform (preloaded with all the Edubuntu education applications) and allows you to optionally install extra educational packages via some scripts. The advanced sanitation guide uses pre-configured images and it allows you to install all the packages (both the Edubuntu platform plus all the extra education packages) in one shot using the image. The next table summarizes all packages installed by each method:

Labdoo recommends installing by cloning images and using the installation tool Labtix (contributed by Labdoo volunteers). Labtix is freely available and anyone can use it. It runs as a 32-bit ISO image on every laptop and it can clone both 32 and 64 bit images. Since Labtix is under continuous development and improvement, please check our FTP server regularly to see if there is a new version available.

Note for advanced users: Labtix has a persistence mode, i.e. you can make your own changes to Labtix and save them. You act as root user in fact. The password (only needed if you "get stuck" in the terminal when booting ) is "labdoo". But beware - as root you can destroy

3 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Labtix or bloat it by too many changes. Labtix fits on a CD when delivered. The tool ISO-snapshot also allows you to create a new ISO-file that takes over possible changes to the system.

Labtix comes with different installation tools and you can find most of them on your desktop. Which tool suits you best is up to you. They all have their strengths and advantages:

Labdoo installer: with a graphical user interface. Auto deploy and content installer: complete and terminal-based installation tool that also automates the deployment of additional content to multiple languages. "2-click" installer: clone images from the File manager SpaceFM with 2 clicks.

On the Labtix desktop, you will find a red folder ''Docs'', where you can find manuals as PDF files. However, we recommend you to watch the individual steps and tools in a YouTube video tutorial.

Sometimes you have to select certain settings in the boot menu because of the hardware, e.g. Toshiba, Nvidia and others. Otherwise, it can happen that Labtix doesn't boot, gets stuck at terminal level (the desktop doesn't appear) or the monitor remains dark. In these cases try the options in Failsafe Mode or Safe Video Mode. This is also explained in the YouTube tutorials below.

All video-tutorials are on our YouTube channel https://www.youtube.com/user/LabdooDACH/playlists and on our FTP server http://ftp.labdoo.org /download/Public/videos/for-technicians/.

If you already have a bootable CD or USB Stick with our Labtix installation environment and Laboo Images for cloning, you can skip this chapter.

Thanks to the Labtix tool (LiveCD), all pre-installed learning content in labdoo systems can be "cloned" quickly and easily to new computers using the so-called images. These images are available in 4 languages (English, Spanish, German, French). So you can select the language in the target country of the IT donation depending on the language and manually upload further learning contents in further languages.

You need two things for that: Labtix bootable media: this can be a CD or USB stick, that you use to boot the Laptop you want to have restored, into the Labtix einvironment. External USB hard drive: to store the cloning images and other learning content from our FTP server (Labdoo also provides an already prepared USB Drive to the volunteers, please contact your local Hub).

Labtix: The Labdoo installation environment

To be able to install older and newer computers with a license-free tool, Labdoo.org has a small solution (live-image) based on the Linux- Version Antix which we have called Labtix (a combination of Labdoo and Antix).

In Labtix you will find everything you need to delete old data on a donated computer or laptop, for fast and automated installation proceses in order to obtain a ready-to-ship computer. Additionally, Labtix provides many tools to diagnose hardware, to analyze and solve problems (CPU/processor, temprerature problems, damaged hard drives, etc.)

You can download the iso file for Labtix from our FTP server here (MD5SUM).

Once you have downloaded the file, you can create a boot media (CD or USB) from the iso file, which you will use to start and prepare (Sanitation process) donated computers

Creating a bootable USB or CD/DVD from the Labtix ISO

The next thing to do is to convert the ISO file into a bootable CD or USB bootstick (simple copying is not enough!). This often works with file managers of your favorite operating system or with additional tools. For further questions consult the web (search for "cd / USB stick create ISO" and your operating system).

A blank 750 MB CD is sufficient for one CD (DVD is not necessary), USB sticks go from 1 GB (but usually 4 GB is the smallest size you can get). Note for technicians: Labtix has a persistence mode, with which you can save your desired configuration. However, this takes up more space, therefore 4 GB or more is better.

WINDOWS: - Download and run a program for creating bootable media. For example, Rufus: https://github.com/pbatard/rufus/releases/download /v3.4/rufus-3.4p.exe (link is external) or another alternative https://alternativeto.net/software/rufus/ (link is external) - Run Rufus, select the USB device, click on the "Select" button and select the labtix.iso file, then click on ''Start''.

LINUX: you will find many useful tools for Linux in the following link: https://wiki.ubuntuusers.de/Brennprogramme/ (link is external)

But the easiest and fastest way is using dd. Once you know the device path to your USB key (in the example /dev/sdb) run: dd if=Labtix.iso of=/dev/sdb bs=1M; sync (see details explained under: https://antixlinux.com/forum-archive/writing-antix-iso-image-on-usb-flas...)

MAC OS: You can use the following procedure: [https://osxdaily.com/2015/06/05/copy-iso-to-usb-drive-mac-os-x-command ] (Here we refer to Internet and search engines).

Labdoo-Cloning images method and additional content

For the Fast Restoration method, you need to clone the Labdoo Images. For cloning, you have to download the images first. Images are copies of a complete, pre-installed system (of already sanitized laptops). Linux has a great feature that other operating systems don't have. You can transfer a system from computer A to computer B - and it runs!

You will find these images online in our Labdoo FTP server http://ftp.labdoo.org/download/install-disk/. You can also download these images from the web browser by selecting the image you want to download, right-click on it, and then select "save link as".

This does not work for folders or for many files! These have to be downloaded individually and of course, this is a lot of work. Simple methods for downloading multiple files for all common operating systems can be found at https://www.labdoo.org/de/content/zugang- zum-ftp-server

Images are large and the download takes a long time, so If you are familiar with FTP clients, we recommend downloading them directly via FTP (sftp, userlabdoo and password labdoo).

Labdoo Images for Cloning

When deciding what image is best for you, you should consider the following aspects:

The CPU/processor architecture of the computer you are currently working on (32 bit or 64 bit). You can easily figure this out with the Labtix environment. It will be displayed in the upper right corner of your desktop (see also the video above). The target language you want to install. The size of the hard disk in the computer to be refurbished. This size is displayed e.g. in the BIOS or after booting Labtix.

The name of an image on the FTP server shows:

There are 4 directories for the 4 available languages: English (EN): http://ftp.labdoo.org/download/install-disk/EN_English_images/ : includes versions for 80, 160 and 250 GB Hard drives. German (DE): http://ftp.labdoo.org/download/install-disk/DE_German_images/ : requires a minimum of 80 GB HardDrive. Spanish (ES): http://ftp.labdoo.org/download/install-disk/ES_Spanish_images/ : requires a minimum of 80 GB HardDrive. French (FR): http://ftp.labdoo.org/download/install-disk/FR_French_images/ :(requires a minimum of 80 GB HardDrive) PAE32 = for 32 Bit-CPUs ; PAE64 = for 64 Bit-CPUs Other 18.04 images Different sizes for 32 BIT-CUPs and 64 Bit-CPUs: http://ftp.labdoo.org/download/archive/18_04_archive/ xx_04_LTS = version of Lubuntu it is based on, either 16.04 LTS (kept for legacy), or 18.04 LTS (to be used from 2018 on).

5 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

imagesThe French and Spanish images occupy 80 GB because they already have the learning content in these languages (Wikis, OER Open Educational ressources,...). The German image is additionally played with German courses, dictionaries in many refugee languages etc..

The English images of 80 Gbs as well, but the larger images (160,250 Gbd) include even more learning contents

Additional learning content

Additional learning content can be added after the installation process if you are not using the autodeploy.sh method that allows you to add additional content during installation. We will come back to this later...

External USB hard disk preparation (1+ TB)

The downloaded images are already unpacked and ready to use. Copy them to an external hard drive or a local server. The USB disk must be formatted to store large files. For example, FAT32 is not possible because FAT32 can only handle files smaller than 4GB. NTFS is the recommended filesystem for an external hard disk.

The automated installation scripts require to be saved to an external hard disk without a parent directory, as they are stored on the FTP server. For further details please refer to the manual http://ftp.labdoo.org/download/install-disk/labdoo%20autodeploy%20and%20...

The Labdoo FTP server allows users to download files and images for Labdoo devices for free. Here are some simple ways to connect to the FTP server. Pick the one that suits you best. For security reasons, Labdoo does not allow unsecured FTP protocol, only the secured SFTP protocol (no ftp, only sftp).

Keep in mind again, that if this all takes too long or is too much work for you, especially for a one-time installation, then give your IT donation into the hands of Labdoo Hubs and helpers!

Note: Labdoo is not responsible for third-party software.

2. Access data to connect to the FTP server

It is more convenient to connect your PC or server directly to the FTP server. Depending on your operating system there are several tools below. We created a user on the FTP server: labdoo with the password labdoo and read permissions (no write permissions), which is available to you for this purpose. If you need write permissions, please contact [email protected] (EN) or [email protected] (DE).

Protocol = sftp (sftp is safer than ftp, so only sftp is available) Server = sftp.labdoo.org Username = labdoo Password = labdoo Path = /var/www/download

3. Integrate into the file manager (Windows, Swish)

6 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Windows does not offer its own way to connect the file manager to an FTP server via the sftp protocol. ftp would be possible, but we do not offer this for security reasons. However, you can use additional programs sftp, e.g. the Swish Add-on for the Windows file manager http://www.swish-sftp.org/(link is external) .

Connect to FTP server using �le manager and Swish (English)

After installing Swish, you have to set up the access to the FTP-Server:

Login to the FTP server: Name - choose a name of your choice; server: sftp.labdoo.org; user: labdoo; path: /var/www/download

Security key: Save and connect - key remains permanently on the PC until changed; Simply connect - key is only saved for this session and will be queried again next time

7 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Enter the password labdoo, now you can use the FTP server like a drive on your PC.

------

4. Filezilla

It is easy to connect your computer to the FTP server with special tools if you need to download massive files. The free FTP client Filezilla can be downloaded here https://filezilla-project.org/.

The start path can be set in the settings under Advanced --> Default directory on the server. Then you don't always have to click through the whole file system.

Enter the access data: Server - sftp://sftp.labdoo.org ; Username labdoo ; Password - labdoo ; Port - 22

Double-click on the Clonezilla icon. Labdoo Images for Cloning are complete images of ready-to-run systems.

Therefore choose the selection image - Image. Labdoo always sets images (not device!) based on versions online.

→ device-image (Labdoo always sets images online, so choose this option)

→ select the storage medium on which the image is located, if necessary with paths and passwords. For external USB disks/sticks this is usually sdb. In Linux the disk drives that start with sda (usually system disk) are named with ascending letters . Pay attention to the instructions on the screen, only plug in USB drives on request and wait for about 5 seconds.

→ Select Expert Mode (we always recommend this mode). The image "remembers" the size of the disk where it came from. For example, if the image came from a 60 GB disk, but is about to be installed on a 40 GB disk, the hint "Target disk too small" appears in Beginner Mode and aborts. In Expert mode you can later check the -icds option, which overrides this check (see below).

→ Select "Restoredisk" to restore an image.

→ Select the image that suits best to your CPU(important is PAE / nonPAE or 32 / 64 Bit, suitable for the CPU)

→ confirm the target hard disk (in most cases sdb or sdc)

→ in "Expert Mode" go to the -icds option from the list and confirm with the space bar ("do not check if target disk is smaller than source disk"), then mark with the space bar (*)

→ Confirm the following entries either with "Enter" or with "Y" (Yes)

→ The installation should start and take about 15 - 60 minutes. Afterwards all data, including operating system, software, settings, learning content etc. are already installed.

In addition to the queries and entries, log lines (white font), notes (green), warnings (yellow) and error messages (red) will appear in the Clonezilla window. Apart from the red error messages, everything else is usually uncritical. And even with the red hints you can ignore the message "unable to find..." towards the end of the cloning process.

Tags: installation clonen image images install clonezilla Installed tools for Labtix

Labtix comes with some useful, pre-installed tools:

SpaceFM. A file manager for the usual file actions and for mounting external devices. It also has plugins to mount shares and burn CDs or DVDs and others. SpaceFM is highly configurable and can be modified with additional plugins. The trashcan is disabled to prevent the accumulation of too much data in persistent mode, but it is addable as a plugin if needed. It should not be removed, because it is part of the desktop's environment!

Conky. A tool for displaying system information on the desktop. The output window is located in the upper right corner. The configuration file is /etc/conky/conky.conf.

Arandr. A tool to configure the screen layout. Very useful if the internal monitor was removed from your device and an external monitor is connected.

ISO-Snapshot. A tool to create an ISO snapshot of the system. The Snapshot saves all changes to the system. While running ISO Snapshot, select the directories that are NOT addable to the snapshot, except the "Desktop" directory that contains the .desktop files. You should move existing snapshots to a directory that you do not want to add to the Snapshot. The Snapshot is saved in /home/snapshot. If you create Snapshot in a non-persistent system (for example, booting from CD-ROM), you should stored it on another device. If there is not enough space to store the snapshot, the storage path can be set to another USB stick. It is possible to install Snapshot on a USB device with UNetbootin or to burn to a CD-ROM or DVD-ROM using SpaceFM's IG-Burn tool plugin.

UNetbootin. A tool to create bootable USB sticks. Start Unetbootin, activate "Diskimage", select the ISO snapshot (should be in /home/snapshot) and select the USB target drive. You should format the USB stick with fat32 and mount it (use SpaceFM for this). After the installation on a thumbdrive, you should use Gparted to check if the boot flag is set correctly!

Networking. Use the command line tool ceni or WICD to set up WLAN. LAN should work by default. Due to the low transfer rate, images should not be installed via WLAN.

Psensor. A tool to control the temperature of CPU, GPU and others.

11 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Gsmartcontrol. A tool for reading the hard disk's S.M.A.R.T. data to check if the hard disk is ok. If you see "red" in the registers, you should use a different hard disk. Tip: If a Seagate hard disk displays thousands of events for reallocating reallocations in the Attributes tab, the drive is not damaged. These hard disks have different firmware, specifically for Lenovo computers that uses the memory bit for reallocation events for other purposes.

Gparted. A great tool for partitioning disks, repairing file systems and copying partitions.

Using the Keyboard Layout Handler on the right side of the panel you can change the keyboard layout with a left mouse click. To make a permanent change, right click and use the "Keyboard Layout Handler Settings". The topmost keyboard layout in the list will be preset at startup. With a left mouse click you can browse the pre-installed keyboard layouts (German, US English, French, Spanish).

Hardinfo. A tool that gives you extensive information about the hardware and software of the computer.

The battery-plugin in the panel gives you information about the status of the battery when the mouse moves over it. With a right mouse click and "Battery Monitor Settings" you can activate the plug-in, if you haven't already done so.

Firefox-esr is a slimmed down version of Firefox and helps you researching the web. It can also display pdf files. By default, it does not collect cookies and does not store data, to avoid bloating with unnecessary data in persistence modeLabtix.

For more information please use the man pages of the help function in the terminal (eg "man gparted" or type in "psensor --help" and press (Enter)) or use the internet.

Desktop Settings: The Labtix desktop environment is based on openbox with the additional lxpanel. If you right-click on the desktop, you can select "Desktop Settings" so you can make changes to the desktop. To install new starters on the desktop, copy them from /usr/share/applications on the desktop. To move icons on the desktop, use Shift + Drag. Please note that in some cases SpaceFM will move the items from the folder. In this case please copy them back. The "Add to Desktop" function of the Lxpanel menu does not work with Openbox. To make changes to Lxpanel, simply click the panel with the right mouse button. Use the Openbox Configuration Manager to change the design of the windows and other general optimizations. For Autostart: Copy the .desktop files to /etc/xdg/autostart or edit /etc/xdg/openbox/autostart for necessary commands.

Persistence Persistence allows you to save changes to a live system like Labtix. An additional file to save all changes of the running system is addable to the USB stick. Enabling persistence on boot will slow down the boot process. Mainly, you sould use Persistence so you can make changes to a live system like Labtix and create a new snapshot to get a new, stable and fast boot live system. You can only installe Persistence on a USB stick. We recommend UNetbootin to install Labtix on a USB stick. USB sticks created with dd cannot be made persistent.

Make a USB stick persistent: Booting from a Labtix USB stick. In the first boot screen, select the options "F5 -> persist_root" and "F8 -> save" and press "Enter" to boot. Follow the instructions to add persistence to the USB stick. Select "manual" as storage method. Adding the persistence file to the USB stick can take several minutes per GB. So please be patient. As long as the option under "F5" is set to "persist_root", the USB stick will boot into persistence mode. Sometimes it is useful to boot without persistence. This can be done by setting the option under "F5" to "none". In Labtix there is a green "Save Poweroff" button on the right side of the panel to save and shut down system changes and a red "Poweroff" button to shut down the computer without saving changes.

gui UEFI Boot only or BIOS locked and UEFI set

[This page explains a solution in case a donated computer can only boot with UEFI or the BIOS is locked (password unknown) and UEFI is set as the boot option. If your computer can boot in legacy mode, you can skip this page].

Back in 2013/2014, there was a technical and legal discussion about SecureBoot and UEFI. The manufacturers argued that only UEFI boot on their computer provides security and therefore must only be used. However, the EU and NGOs went to court and the judges decided that the computer manufacturers had to re-open the BIOS settings so that users could choose whether to use the UEFI boot, the legacy boot (the "old" boot) or both as boot options. Computers that were produced before the "UEFI only" decision and after the old flexibility decision have no problem installing with Labtix and prepared Labdoo images.

However, if the computer was manufactured in the "UEFI only" period in 2013/2014, this may cause problems when installing a Lubuntu-based installation. Our Labdoo images are set up for legacy boot, not for UEFI boot (although Lubuntu could). We have described a solution for these specific UEFI-only machines here.

Another use case is a locked BIOS. A computer has been donated, but a BIOS password has not been removed and is unknown. If the boot option in the BIOS is set to "UEFI / Secure Boot Only" and cannot be switched to "Legacy Boot" because of the password lock, you can run the installation process described below and then use the computer for Labdoo.

If our solution is too difficult for you, please contact Labdoo helpers or hubs in your country / region and ask them for support.

You can use the installation tool Labtix (recommended, supports UEFI-Boot) or Parted Magic. PXE is not possible because you have to select certain options during the installation process and PXE does not allow access to these settings.

The installation sequence is rough:

First install a small Xubuntu based image via cloning in a partition (Xubuntu is able to UEFI boot); a prepared image is available on FTP server http://ftp.labdoo.org/download/install-disk/special_images/, Next ,install in a second partition of one of our Labdoo images with slightly different settings than usual. Change the grub boot file. After that, the system will boot and a user will not even notice that this is a special "UEFI only" laptop. This solution only works for 80 GB disc-drives or bigger.

So here are the steps in details:

1. Download the special UEFI-Boot image, available on our FTP-Server http://ftp.labdoo.org/download/install-disk/special_images/ and copy it to a local USB-drive or any local server. 2. Start Labtix, run the Clonezilla tool (icon on the Labtix desktop) and make the drive with the special UEFI image available - Important: Use "expert mode" and "restoredisk", mark the option -icds . For experts: Or install Xubuntu (I think all other UEFI based * buntu do it too) in UEFI mode on the device. 3. If you use the prepared UEFI image, the size of the partition sda2 is set to 80 GB by default. A Labdoo image for 80 GB fits. If you want to install an image for a 160 GB or 250 GB hard drive, you have to enlarge the partition sda2 with GParted. 4. Shut down the computer and restart it with Labtix. 5. Start Clonezilla to replace sda2(!) of the installed UEFI-Boot image / Xubuntu by replacing "restoreparts" with sda1 of the Labdoo- image you want to install. Make sure you choose the target-partition sda2 when asked and the "-icds"-option in "Clonezilla advanced extra parameters". Make sure the option "-k Do NOT create a partition table..." is checked. 6. After installing sda2, use GParted to maximize sda2. Check if the "boot"- and "esp"-flags are set to sda1. To retrieve the UUID of sda2 right-click on it and select "Information". Mark the UUID and copy it with "Ctrl" + "C" to the clipboard. 7. Edit /EFI/ubuntu/grub.cfg in the EFI-bootpartition ( usually sda1, the small partition with 512MB ) with the editor Geany and replace the given UUID with the UUID of sda2 you copied by GParted. E.g. open SpaceFM -> sda1 -> navigate to /EFI/ubuntu/grub.cfg -> right mouse click -> open > Geany editor -> in line 1 you will see a UUID -> mark and paste the new UUID from the clipboard. Don't forget to save the file before closing Geany editor. 8. Shut down and restart the computer. Now it should start in UEFI mode and users will see the Labdoo login after a short time.

This description is very technical, but it works. If you know a simpler solution, please feel free to contact us. A special thank you goes to helpers from hub Rhein-Ruhr (Germany) for noticing and solving this specific problem.

Introduction

This wiki will lead you through the process of sanitizing Labdoo laptops using ready-to-use images from the network. It allows you to sanitize laptops using a fast and efficient cloning process and is also very helpful if you are dealing with a large number of laptops. However, this process is quite more complex at the same time and that is why we consider it an advanced method. If you are new to Labdoo and do not have much experience with computers, we recommend you to use the Simple Sanitation Method, but if you are up for learning a great way to install a powerful software in a computer, this is your guide.

Images are a complete software copy of an installed Labdoo computer containing everything, from the operating system, software, educational content to al optimized settings. The cloning process takes care of everything for you in one shot, except for adopting the final configuration to the country of the destination edoovillage (language and keyboard) and setting the hostname.

In the next section you will find a step by step description of the Sanitation process based on images.

How to use a Labdoo PXE server to sanitize laptops

[Note: This section assumes you have a Labdoo PXE server with you (because you either created one by following the instruction in the section below "Steps to create a new Labdoo PXE server" or because another hub gave you the Labdoo PXE server so that you can use it to sanitize your laptop)]

If you already have a Labdoo PXE server, please read the "PXE Process in detail" document that you can download from this link. This guide explains step by step how to use the PXE server to sanitize laptops. You can also download from this link the "Labdoo Process Slip", a handy

slip which will allow you to track each laptop technical description as explained in the "PXE Process in detail" document.

Steps to create a new Labdoo PXE server

# Installbox ########################################

The Installbox set-up allows you to automatically install Linux clients on a large scale.

### Pre-Requirements

- A laptop with wireless LAN and gigabit ethernet port - A gigabit switch - Network cables to connect the clients - Wireless internet access where you are NOT using the IPv4 network address 192.168.20.0/24

# Installbox Setup ########################################

- Download the customized ISO image: GET-LATEST-VERSION-FROM-WEB.iso - Either burn the image to a CD or write it to a USB key using dd if=debian-jessie-installbox.iso of=/dev/sdb (replace sdb with the device node of your USB stick, if necessary). - Boot the laptop using the CD or the USB stick. - Please do not connect the ethernet cable yet. - Select the option "Install" during boot. - You will be asked to select the keyboard layout, select the one that fits best for you. - During network set-up please select the wireless interface. There should be two interfaces on the list: eth0 (which is ethernet, don't select this one!) and wlan0. Note: If you do not see those two interfaces here, please abort the installation process. It means that your device is not supported. - When you have selected wlan0, the installer will search for wireless networks available. Select your network. Most modern wireless networks use WPA/PSK for authentication, so if you are not sure, you can select this option. - Type in your Wireless password in the next step. Please note that it is displayed in a clear text. - Relax, the rest of the installation should work fully automated. - After a while the device reboots, so you can now connect an ethernet cable from the laptop's installation box to the gigabit switch. - You should now be able to connect any client to the switch and select ethernet boot. On Lenovo, you can press F12 and choose the network interface as a boot device. - On the install box, an NFS export has been created on /exports. This will be available to all clients on the LAN and should contain the Clonezilla images.

# PXE Boot Options ########################################

When you boot a client, the boot menu will show the following options:

- Clonezilla Autorestore x86 This should be started on a client where you want to apply the default image. No interaction needed, all existing data will be deleted. It will restore an image called Linux-x86 which must be available in /exports on the install box.

- Clonezilla Autorestore x86_64 Same as Autorestore x86 but for the 64bit variant. It will automatically restore an image called Linux-x86_64

- Preseed x86 Prepare a 32bit master installation

- Preseed x86_64 Prepare a 64bit master installation

- Clonezilla Autosave x86 Create an image of a master installation. It will automatically be written to the NFS share /exports under the name Linux-x86. Note: This will overwrite an existing image of the same name in the install box.

- Clonezilla Autosave x86_64 Same as Autosave x68 but for the 64bit variant. It will automatically write a disk image to the install box at /exports/Linux-x86_64. Note: This will overwrite an existing image of the same name on the install box.

- Clonezilla Live Just the default live image with all options and the NFS share already mounted.

- SystemRescueCD A universal system recovery toolbox. It also contains GParted for manual partitioning. To start GParted, simply type startx and then click on the GParted icon in the taskbar.

- Boot and Nuke starts dban and will automatically wipe all data on disk.

Note: you can press the tab key on all options in order to change settings manually. To permanently adjust the file, edit /var/lib/tftpboot/prd/pxelinux.cfg/default on the installbox.

# Workflow ########################################

After you have set up the install box a typical workflow would be the following:

1. Create a master image

- Choose another laptop on which you want to create the master image. - Connect the laptop to a port on the gigabit switch. - Follow the steps described in the 'Prepare Master Image' section.

Alternatively, you can download a prepared master image. See the 'Image Creation Cutoff' section below for further details.

2. Provision laptops with the newly created master image

14 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

- after the master image has been stored on the install box, choose the relevant Clonezilla Autorestore option from the PXE menu

Once you have created a master image, there is no need to re-create it other than changes that need to be done to it. Next time, you can just start provisioning clients using the Autorestore option.

Hint: if you are not sure, just create a master image for the x86 architecture. This should work on nearly every machine.

# Image Creation Cutoff ########################################

If you do not want to prepare an image on your own, you can download the prebuild image for the x86 architecture.

To do so, execute the following commands in the install box:

sudo wget -c GET-LATEST-VERSION-AS.tar.gz -O /exports/linux-x86.tar.gz sudo tar xvzf /exports/linux-x86.tar.gz -C /exports/

Note: the image to download might take a long time, it depends on your internet connection. If the download is interrupted for some reason, you can resume it by executing exactly the wget command from above again.

This image is set up for the Swiss-German keyboard layout. If you want to customize it: - Deploy a machine using the 'Clonezilla Autorestore x86' function. - Boot it and make your customization. - Boot the SystemRescueCD and start GParted. - Shrink the root partition to ~ 30000MB. - Remove any existing version of the image by running sudo rm -rf /exports/Linux-x86 on the install box. - Reboot the client that contains your modifications and select the Clonezilla Autosave option for x86. This will save your modified version to the install box.

# Prepare Master Image ########################################

In order to develop a master image from scratch, please make sure that the install box in your laptop has a working wireless LAN internet connection.

### Preseed

On a client that connects to the gigabit switch, start the pxe boot and select either Preseed for x86 or x86_64. This will set up an install base of ubuntu with a user "Labdoo" and a password "Labdoo".

After preseeding, boot into the newly installed system and apply the customization from:

http://ftp.labdoo.org/download/install-disk/installskripts/

If you want to modify the preseed file, e.g. to set up a different user account, just edit /var/lib/tftpboot/trusty/preseed.cfg

Hint: To change the keyboard layout (which defaults to us), simply run dpkg-reconfigure keyboard-configuration after installation.

### Creating the Image

When the client has been set up according to your needs, reboot and select the relevant Clonezilla Autosave option that fits best the architecture of your master set-up.

This will automatically save an image to the install box that will be applied later to other clients using the Clonezilla Autorestore function for that architecture.

Note: This automated process has been optimized for image installations on systems with at least 40GB HDD/SSD of space. If you need to install it on machines with smaller disks, please shrink the root partition before creating the image.

# Image Requirements ########################################

If you do not want to use the images that eventually work with the install box setup, please make sure that your images fulfill the following requirements:

- images should be deployed automatically using this setup and must have the following partition layout: /dev/sda1 - swap (suggested size 2GB) /dev/sda2 - root / ext4 - after the master preparation, please shrink the root partition to its minimal size possible. This ensures that the image will be deployable on small drives as well.

# Resetting the Installbox ########################################

You can reset the changes made to the install box default settings at any time by running /usr/local/sbin/applypuppet as root.

# Making of the Installbox ISO ########################################

This step is not necessary, it is just for informational purposes. It describes how the ISO for the install box was created.

apt-get install -y bsdtar genisoimage syslinux-utils cd ~ rm -rf cd mkdir cd wget GET-LATEST-VERSION-FROM-WEB.iso bsdtar -C cd -xf firmware-8.2.0-i386-netinst.iso vi cd/isolinux/txt.cfg - append vga=788 initrd=/install.386/initrd.gz --- quiet + append vga=788 initrd=/install.386/initrd.gz url=GET-LATEST-VERSION-FROM-WEB.cfg locale=en_US.UTF-8 ipv6.disable=1 debconf_debug=5 netcfg/get_domain=domain.example netcfg/dhcp_timeout=60 netcfg/get_hostname=installbox --- quiet quit vi with ESC :wq! vi cd/isolinux/gtk.cfg

# Additional Notes ########################################

- There is a script available on the installbox called /usr/local/sbin/pxesync. It can sync the files needed for PXE boot for the Ubuntu and Debian distributions.

Introduction

This brief document describes the process of sanitizing a laptop according to the Simple Method.

[TIPS. If you'd like to get tips on how to collect unused laptops from your local community, please click here. After the laptop gets sanitized, you can click here to learn different ways to package the laptops to get them ready for schools that needs them. If you get stuck in any of these steps during the sanitizing process, you can post your questions in the wall of the Labdoo QA Team so that others can help you.]

Labdoo - installing Lubuntu (English)

Sanitation Steps

The current standard process of sanitizing a laptop is as follows:

1. If the laptop is not already tagged with a Labdoo ID number, please follow the instructions under "tagging a laptop" page. Make sure you print 3 labels and attach two of them to the laptop and one to the AC adapter following the instructions that you will find on the website. 2. Download the Ubuntu Mate 20.04 release from this link (this is a large .iso image): http://cdimage.ubuntu.com/ubuntu-mate/releases/20.04/release/HEADER.html 3. Burn the downloaded file into a CD. Make sure you burn the downloaded file as an ISO image. If you don't know how to do this, you can follow the instructions from any of these links depending on the type of computer you use to burn the CD: (Note: you can either use a CD or a DVD, the burning process is the same. We recommend to use a CD because some older computers do not accept DVD.) - Burning a CD using a Windows computer. - Burning a CD using an Ubuntu computer. - Burning a CD using a Apple/Mac computer. 4. Insert the Lubuntu CD into the laptop you intend to sanitize and boot the laptop from the CD. Upon booting the laptop with the CD, you should see the Linux installation menu. If you don't see it, you need to enter into the bios of the laptop and change your computer's booting order to make sure that it first boots from the CD. For more information on how to configure the bios, see this page. 5. Upon seeing the Lubuntu installation menu, start by selecting the installation language; for instance, choose “English”. 6. Select “Install Lubuntu”. 7. Select the language to be installed on the laptop. If you don't know the destination country, select “English”. If you know the destination country, select that country's language. 8. In the "Wireless" screen, if you have an internet connection, you may select the network you use from the list and enter its password. Otherwise, leave it as default. 9. The next window is just to confirm that the laptop fit into the minimum Hard Drive requirement. Hit "continue" once. 10. Now we are going to do a small trick to ensure we completely remove any previous private data from the computer. Please press at the same time the keys 'Alt + CTRL + F3'. This will take you to a terminal window. In this terminal window, please enter the following command first: sudo apt-get install coreutils [press enter]. Once this command is executed, run this other command: sudo shred /dev/sda -f -v --iterations=2 [press enter]. (If this second command does not work, you can try with 'hda' instead of 'sda', like this: sudo shred /dev/hda -f -v --iterations=2.) This second command launches a process that will run for about 1 hour or so and overwrites the disk with random values. After you finish with this

16 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

process, press at the same time the keys 'Alt + CTRL + F7' to continue the installation process and go to the next step. (Please see the video in this page for a complementary illdustration of this step.) Note: If the above does not work, an alternative method is to reboot the computer and select the option "Try Ubuntu" to boot Ubuntu in trial mode. Then once Ubuntu is booted, open a terminal by pressing the keys [Ctrl+Alt+T] at the same time. In this terminal, type the same 'shred' commands described in the previous paragraph. Once the shred process is completed, reboot again and redo all the installation steps again but omitting this step. 11. Select the destination country. If you don't know it, pick the country where you are. 12. When it prompes “detect keyboard”, select “No”. 13. On the next screen, pick the origin country of your keyboard. 14. Press “cancel” when the network is being configured (there is no need to do network installation since you have the CD and the updates are installed later). 15. When you are asked for “Your name”, please enter the word “Labdoo”. 16. When you are asked for the “Your computer name”, please enter the word labdoo with its Labdoo ID number (eg. labdoo_000003454). 17. When you are asked for the “username”, please enter the word “labdoo”. 18. When you are asked for the “password”, please enter the word “labdooadmin”. 19. When you are asked for the “Confirm your password”, please enter the word “labdooadmin”. 20. Select any time zone you want if the system requests. 21. When you are asked for the “Partitioning method”, please select “Guided – use entire disk”. 22. When you are asked for HTTP proxy information, please leave it empty and just press “Continue”. 23. When it says “Install the GRUB boot loader”, please say “Yes”. 24. When it says “Is the system clock set to UTC”, please say “Yes”. 25. This completes the installation of the basic operating system. Next, reboot the machine and log into the Lubuntu system using the username "Labdoo" and the password “Labdoo”. Once you are into the Lubuntu system, make sure also that the laptop is connected to the Internet, via Ethernet cable or via WIFI. Finally, type ALT+CTRL+t to open a terminal window, and in it, type the following commands:

sudo apt-get update [and press ENTER] sudo apt-get install edubuntu-desktop libreoffice [and press ENTER] sudo apt-get upgrade [and press ENTER] The last two commands could take from a few minutes up to an hour to complete.

26. Install the Labdoo logo as a background image in your desktop to give it a friendly look. You can download the Labdoo desktop image from this page and then by right-clicking on your computer desktop you can select the option "Desktop preferences" and install the image. 27. Now, you can install the additional educational software (such as an offline version of the Wikipedia, and more educational applications) by following the instructions in this page. This step is not mandatory as the laptop already has a good number of educational applications at this point, but it's a good thing to do.

What to expect next

Congratulations! You have now successfully completed your laptop drive campaign and sanitized your laptops, so they are now ready to be packed and travel. Please go to the Packaging the laptop for travelling section to learn how to get the laptops ready for door trips.

If you are traveling yourself to a school project, you can bring the laptops in your luggage. Try to distribute as many laptops to as many people traveling with you as possible because some countries have a limit on the number of laptops that can be carried per person. If you are not traveling, then get in touch with one of the Labdoo hubs (for instance, one which is closest to you) from the hubs list. A Labdoo hub will help you decide which school your laptop should be sent to and he will also help you to get in touch with the travelers going to that school so the laptops can be picked up from you.

In this section, we will describe the set of post-installation steps. These steps must be followed once you have completed the Labdoo image installation (as described in the previous sections) to ensure that the system is properly configured and ready to be delivered to a destination school. You can rely on both the text description as well as the videos underneath to complete these steps.

Video 2. Adapt system files hosts and hostname.

Labdoo - change hostname (English)

[Download this video]

1. Change the host name. The computer's host name must be set to the Labdoo identifier. First, you need to tag the laptop by following the steps described under this page. Once you tagged the computer, modify the file hosts as follows: Open a terminal (press CTL + Alt + T) and type sudo nano /etc/hosts (Enter) Change the line "127.0.0.1 labdoo-123456789" to this file, substituting 123456789 with the 9 digit Labdoo ID of the laptop already obtained in the moment you tagged it. Save the file by pressing CTL + o (the letter o, not the number 0 (Enter)) Leave the editor by pressing CTL + x Now open a terminal (press CTL + Alt + T) and type sudo nano /etc/hostname (Enter) Change the host name to the value "labdoo-123456789", substituting 123456789 for the Labdoo ID of the laptop already obtained in the moment you tagged it. Save the file by pressing CTL + o (the letter o, not the number 0) (Enter) Leave the editor by pressing CTL + x Restart the laptop to see the name that its been changed. 2. Check the graphic resolution. Go to Preferences → Monitor Settings → select the resolution you need or stay with the resolution already set → Apply. 3. Check the keyboard and language settings. Right mouse click on the country language icon that you will in the launch bar → select "Keyboard Layout Handler" Settings → uncheck "Keep system layout" → click '+Add' to add up to 4 keyboard layouts or '-Remove' to remove them → Close. 4. Install additional languages. Go to the menu and select: Preferences → Language Support → Install/remove Languages → add a hook to the language(s) you want to add (remove a language by removing the hook) → Apply Changes. The computer must be connected to the Internet so that you can download and install the language(s).

To change to another user language, select the language you want and move it with the mouse (keep left button pressed) to the top of the language list and drop it → Apply System Wide → all users will use this language. For more details refer also to the (L)Ubuntu manuals under the laptop folder /home/labdoo/Public/manuals-ubuntu.

HINT. If you send the computer to a country using a "non-Latin" alphabet you should stay with the English language. This way the user can easily learn about the keyboard switch. You also need to understand the foreign language and know the keyboard layout to use the computer. E.g. typing the password "Labdoo" using the Chinese or Arabian keyboard layouts will result in something different and will not be accepted as a password.

Regional Formats. Click on the tab "regional formats", click on the triangle → select the setting you need(will change the format of the time/date and currency) → Apply System-Wide.

As explained in "How To Sanitize a Laptop" https://www.labdoo.org/content/how-sanitize-laptop (please review it if you haven't seen it) There are several contents that are part of the Labdoo Computers when sanitizing a computer.

If you sanitized your computer following any of the "Fast Restoration Methods", the images you install already include these additional educational packages, so you don't need to do anything else.

However, if you sanitized the computer using the "Step-by-Step method", the following sections will guide you through the process of manually installing the additional educational packages.

packages installation Installing the RACHEL Education Package

RACHEL is a free collection of powerful educational content available in several languages. It includes packages like Wikipedia, Khan Academy, Edison for Robotics, CK-12 Textbooks, UNESCO's IICBA Electronic Library, MedlinePlus Medical Encyclopedia, Great Books of the World, OLPC Educational Packages, or MIT Scratch, among many others. To get an overview of what a package includes, please refer to the project's page at http://rachelfriends.org/ or check OER2GO's list of educational software from http://oer2go.org/.

RACHEL takes about 20-25GB of disk space and it is recommended to install only on disk drives of 50GB or higher.

To install RACHEL, first, you need to download the package into your local disk. If you are sanitizing a Labdoo laptop or tablet, we recommend you installing RACHEL by downloading it from http://ftp.labdoo.org/download/install-disk/wiki-archive/wikis/. In this FTP server, you will find zipped (compressed) files with extension *.tar.gz organized by languages (for instance, "EN" for English, "FR" for French, etc.). Download as many compressed files as you think are necessary for the school of destination your laptops/tablets will be deployed at.

Installing RACHEL on a Laptop Once you have downloaded the RACHEL package(s), create a new folder called "wikis" inside /home/labdoo/Public/ and unzip RACHEL there (the downloading and unzipping operations could take some time depending on the speed of your network and computer). Once unzipped, double click on the file /home/labdoo/Public/wikis/RACHEL-EN/bin/www/starthere.html to open a web browser that will take you to the RACHEL's start page.

To create easier access for users, we recommend you to make the default web browser page point to RACHEL's initial page. For that, open the web browser (these instructions are for Firefox but similar steps apply to other browsers) and go to:

File => Open File [ navigate to /home/labdoo/Public/wikis/bin/www/starthere.html ] => Open

Then go to:

Edit => Preferences [ opens a window for the settings, click on "Use current Pages" and close the tab "Preferences" ]

Please repeat any of the configuration steps for both the 'Labdoo' and the 'student' users (if they are both available on your laptop).

Note. The first folder "Wikipedia for Schools" is equivalent to the Xowa package; hence, if your Labdoo laptop already has Xowa installed, you can remove this folder from RACHEL, which will give you back 6,5 GB of disk space.

Installing RACHEL on a Tablet

The RACHEL package includes also an installation file for Android (apk file): http://rachelfriends.org/downloads/public_ftp/. However, notice that as long as you read the RACHEL content in a web browser from a tablet, it is not necessary to install this apk-file. That means that you can just copy and unzip the RACHEL file to the tablet and open the file "starthere.html" from the tablet's web browser. With this method, you can use RACHEL in any tablet (not just Android) just by using the tablet's web browser. Some tablets may not have enough built-in disk space to store RACHEL. If that is the case, you need to include an external storage card and install RACHEL in it.

Note. RACHEL is much more than just content for a web browser as it also includes executable files. Some of these executable files may not be compatible with Labdoo's operating system. However, these additional programs do not take much disk space, and hence we recommend to leave them where they are so that schools abroad can still have the option to copy these tools to other compatible platforms and use them.

Tags: rachel wiki Installing Education Packages Using Scripts

In addition to installing the base Edubuntu education package, users are encouraged to also install a set of additional valuable educational resources. These additional resources are installed by executing a set of scripts through a simple process described in this section. If you have questions or suggestions please write your messages directly in the Labdoo QA Team Wall.

List of Available Scripts

All Labdoo scripts can be downloaded from the FTP server http://ftp.labdoo.org/download/install-disk/installskripts/ To execute a script the computer must be connected to the Internet (LAN or WLAN).

There are scripts for the installation of further learning software, learning content and codecs (please note the legal situation). We strongly recommend the use of these scripts to upgrade a pure Lubuntu installation:

installscript-content.sh http://ftp.labdoo.org/download/install-disk/installskripts/installscript... (recommended, very useful; script installs learning content, offline wikis and manuals, connection of a USB stick >= 16 GB useful) installscript-software.sh http://ftp.labdoo.org/download/install-disk/installskripts/installscript... (recommended, very useful; script installs further educational software, barrier-free access for blind people, tools and much more).

Additional helpful scripts (optional):

installscript-codecs.sh http://ftp.labdoo.org/download/install-disk/installskripts/installscript... (please note the legal situation in the country where the computer is installed!; script installs additional codecs and multimedia software for audio and video) set-rights-folder-files-Public-correct.sh http://ftp.labdoo.org/download/install-disk/installskripts/set-rights-fo... (This script sets the rights in the folder /home/labdoo/Public, so that the student users will have access to the content in this folder. This may be useful if you install further learning content in the folder /Public) check_cpu_32_or_64_bits_PAE_or_nonPAE.sh http://ftp.labdoo.org/download/install-disk/installskripts/check_cpu_32_... (This script will tell you what type of CPU is installed in your computer. It does not include any educational software, it is only for cloning images)

19 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

There are scripts that are only useful in certain cases (optional, only for experienced users):

installscript-xowa.sh http://ftp.labdoo.org/download/install-disk/installskripts/installscript... (This script reinstalls the offline wiki tool Xowa and sets folder rights correctly) installscript-virtualbox.sh http://ftp.labdoo.org/download/install-disk/installskripts/installscript... (This script installs VirtualBox to use guest operating systems like Windows in parallel, min. 2 GB RAM and Dual Core CPU is required).

The following steps describe shortly how to install a script:

Step 1. Download a Script - From an already sanitized Labdoo laptop, open the web browser and go to this link: http://ftp.labdoo.org/download/install-disk/installskripts - Right-click with your mouse on the link of the script that you want to install. - Select "Save link as" and save the file in the desktop of a Labdoo laptop (/home/labdoo/Desktop).

Step 2. Execute a Script Open a terminal (press CTRL + Alt + T at the same time) and execute the following commands:

cd ~/Desktop ls chmod u+x ./installscript-content.sh sudo ./installscript-content.sh

(change the script 'installscript-content.sh' to the name of the script you want to install.)

This will run the script and automatically install a new educational software package.

Hint. Some scripts will ask for passwords or settings through the installation process. Please be aware if you need to provide the necessary inputs.

Hint. Some scripts are fast, some need hours. It depends on the speed of your internal connection and on the speed of the laptop.

What scripts are not able to solve

The Labdoo team is working to improve and extend capability of the scripts. At that moment the following steps have to be adjust manually:

General for all desktops and for all user (labdoo and student):

Firefox: 4 tabs should be added manually and pre-set in Preferences -> General

file:///home/labdoo/Public/manuals/index-manuals.html about:startpage

Firefox: install add-on Fireclam (virus protection) Calibre: import eBooks for die users labdoo and student

Add more plug-ins to the task bar (LXDEDesktop / Lubuntu):

Right mouse click on the task bar → Add/Remove Panel Items → +Add → select the plug-in you want → +Add → Suggested plug-ins and their sequence from right to left:

Menu (already installed) Application Launch Bar (already installedt) Spacer (already installed) Desktop pager (already installed) Spacer (already installed) Task Bar (already installed) Volume control (already installed) System tray (already installed) Indicator Applets (already installed) Keyboard Layout Handler (to be installed) Resource Monitors (to be installed) Network Status Monitor (to be installed) Manage Network (to be installed) Digital clock (already installed) Application Launch bar (already installed)

The plug-ins can be moved within the task bar, right mouse click on task bar→ Add/Remove Panel Items → mark plug-in in window → click on Up or Down until the plug-in reached its position.

Wallpapers

On the FTP server are wallpapers under http://ftp.labdoo.org/download/archive/labdoo-wallpaper/ that you can download and use freely. Depending on the desktop version that you have, copy the wallpapers into different folders (with file manager with superuser rights)

LXDE: /usr/share/lubuntu/wallpaper Xfce: /usr/share/backgrounds/xfce MATE to 4/16 LTS: /usr/share/background/Mate/desktop MATE from 18.04 LTS: /usr/share/background/ubuntu-mate-common

Optional: Use the scripts in the hidden folder .scripts (if LXDE and Xfce desktops are installed simultaneously)

If case LXDE, Xfce and / or Mate are installed as desktops in parallel, we recommend

create a hidden folder /home/labdoo/.scripts Copy the two scripts installscript-software.sh and installscript-codecs.sh there and make them executable if case you are in Xfce Desktop: create a starter for both scripts, set icon, links, execute etc.

Without this measure, either starter and scripts would be double on the desktop. And will be confusing wich to execute with Xfce.

Optional: Xfce and / or Mate Desktop

In case you install Xfce 4 and / or Mate Desktop, several optimizations can be made, see https://www.labdoo.org/content/mate-undoder-xfce- desktop-einstellen

Important: For Lubuntu 14.04 LTS ff.: Keyboard Layout handler → right mouse click on Icon in task bar → settings → Important! Remove hook in „Keep system layout“, as otherwise you are not able to install additional keyboard layouts.

Important: For 14.04 LTS ff.: Use Light Locker to switch off the screen locker (for user labdoo and student)

only for Lubuntu 12.04 LTS

Browser: Standard browser in Lubuntu 12.04 LTS is still Chrome, later Lubuntu releases use Firefox as browser. To avoid user confusion you should install Firefox for Lubuntu 12.04 LTS and set Firefox as standard browser, please:

remove Chromium in application launch bar and add Firefox → right mouse click → change Set Firefox as standard browser → Preferences → Preferred Application → Browser → Firefox (for both user labdoo and student) optional: uninstall Chromium

For Lubuntu 12.04 LTS: The keyboard layout in Lubuntu 12.04 LTS was buggy. Due to this our script installs the program LXKeymap. Add a starter on the desktop to enable keyboard switching for 12.04 LTS.

Only if desktops Unity and Gnome are installed

Unity (Ubuntu Default Desktop) Compiz: Optimize performance Use CompizConfigSettingManager to set General → OpenGL → Set to "Fast" Effects → Switch Animation and Fading off (remove the hook) Add 4 workspaces for both users labdoo and student → open System Settings → Appearance → behaviour → mark activate workspaces

Unity: To show the menus in a program window, not in the top bar (like Apple do), to be changed for both users labdoo and student → Open System settings → Appearance → Behaviour → show the menus for a window → mark "in the window's title" User name is not shown in the top bar on screen → open a terminal → type → dconf-editor → Enter In dconf-editor → apps → indicator-session → hook in show-real-name-on-panel → close window

remove Amazon Icon in application bar (right mouse click on the icon → remove)

Tags: scripts setting Make a script executable

Make a script executable -> right click on the script on the desktop -> properties -> Permissions (2nd tab) -> Execute: Only owner and group -> ok

For security reasons you should run the scripts as administrator (super-user). For some tasks like installing software it is even mandatory. Unless otherwise specified:

Execute a script as administrator (super-user) (href="https://dev.labdoo.org/content/terminalfenster-%C3%B6ffnen") -> open terminal -> cd desktop (enter) to get into the folder /desktop -> sudo ./installscript...sh (the name of the script incl. .sh at the end) (Enter) -> if necessary enter password and let it run.

1st Tip: after entering cd Desktop type ls in terminal -> list all files in the folder Desktop; -> mark the script name with the mouse -> either press at the same time Shift + CTL + c or right mouse click "copy" -> type sudo ./ ; either press at the same time Shift + CTL + v or right mouse click "paste" so you do not have to type the name of the script.

2nd Tip If the installscript-content.sh is executed, it is worth using a USB stick or an external USB hard disk. This must be "mounted", i.e. it is easiest to open and check it once with the file manager PacManFM, or a folder Public is created in the top directory. The script for the learning content copies approx. 9 GB of data to the USB stick the first time and then to the hard disk of the Labdoo computer. This does not save any time. From the 2nd computer on, however, only a short comparison with changes on the FTP server is made and then copied from the USB drive to the hard disk. This saves you considerable time and relieves the data traffic with the FTP server.

Required entries: Some scripts require passwords to be entered or settings to be confirmed. Therefore, please keep an eye on the scripts at the beginning, so that these entries are made by the user.

Runtime: The runtimes of the scripts are very different and depend on the speed of your internet connection and the Labdoo computer. Especially the scripts for software and content can run 2 to 4 hours the first time. This gives an indication of what the children would have missed if the scripts had not reloaded these things.

Ending a script: As soon as the cursor appears again in the terminal in a line after labdoo@000004xxxx:~$ the script has been successfully processed. Then the terminal window can be closed or used for a new task.

Repeating the last input: With the "arrow up ↑" key you can scroll through the last input in the terminal, sometimes saves a lot of typing.

Execute a script several times: The scripts are all designed to be executed as often as you like and to do useful work. For example, the scripts for the installation of software also carry out an update of the virus scanner ClamAV or the content script compares with the FTP server to see if there have been any changes.

But there are also steps that the scripts cannot (yet) complete. More about this in the next chapter.

Tags: scripts installation content Installing Xowa Wikis

Over 800 offline wikis are available via Xowa tool. This allows children to read in wikis even when they do not have internet access. We install a Wikipedia suitable for children called Wikidoo. In the Labdoo images, Wikidoo and Xowa are already included with 4 wikis (Simple English), otherwise, it can be installed by script, see a href="../content/installing-education-packages-using-scripts".

Path to Xowa: /home/labdoo/Public/xowa Path of the Xowa Wikis: /home/labdoo/Public/xowa/wiki

To start Xowa there is already a Xowa starter (Xowa icon) on the desktop, which can be started by double-clicking. If you need more wikis, you can download them from our FTP server or from Xowa itself:

Download a wiki as a zipped file from the Labdoo FTP server

Please check first if the required Xowa wiki bundle is available as a tar.gz file on our FTP server http://ftp.labdoo.org/download/install-disk/wiki- archive/xowa-wikis/. If not, send an email to [email protected] and we will try to prepare and upload the Xowa wiki bundle you need.

Once you download the zipped "tar.gz" file from the FTP server above, please unzip it into the folder ~/home/labdoo/Public/xowa/wiki. Finally, the script set-rights-folder-files-Public-correct.sh is executed (by double-clicking; this gives all users access to the contents in the /Public folder).

Alternatively, if you want to download and install XOWA by yourself, there are 2 ways:

Version 1: text only, no graphics or pictures (please pay attention to the size of the wiki in the table, can range from 100 KB to 40 GB); images can be installed for a wiki version 1 via Import Offline (see below). Version 2: includes version 1 plus linked pictures and graphics (recommended, as it is more user-friendly and informative, although it needs more disk space)

After you have installed Xowa, you can start it by double clicking on the Xowa starter icon that you will find in the laptop desktop. There are 2 ways to download Wiki. To do so, start Xowa and scroll down to "Links" on the main page of the program:

Import Online (corresponds to version 1): Start Xowa → scroll down to links → Import Online → scroll down to the wiki list → search for the English name of the language → in column set up click on the link download → download starts, may take hours depending on wiki size → last delete the folder /dump in /home/labdoo/Public/xowa/wiki. Import Offline (supports versions 1 and 2): This is the recommended method. We recommend to download by the script → scroll down to links → Import Offline → select the desired wiki and language → Category system: version 2 → Import: click on Generate script → repeat → until the script is complete, then click on "Run script".

22 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Be careful! Not every wiki is available in every language, often Wikivoyage is missing. If you click on a non-existent wiki during offline import, a script will be created, but it will crash during execution. So please check if the Wiki exists. Here is a trick: Open 2 tabs (file → New Tab); with one you go to the online import table, with the other to the offline import page. In the online page, you can search for the language and wikis by clicking Edit →. This way you can quickly see if a specific wiki exists.

Matching wikis to Xowa The Xowa wikis can only be used with the same Xowa version that was used to download them. Labdoo updates Xowa version every 6 months (at the beginning and middle of the year) to minimize the work of keeping wikis up-to-date.

So if you download new wikis at home and want to take a USB stick to an Edoovillage, make sure you do this process with the same Xowa version that was installed in the laptops deployed at that Edoovillage.

Clean up: After importing, there is a subfolder /dump in the folder /xowa/wiki. This trash contains downloaded wikis to delete after the installation because they only block space unnecessarily.

Rights of the Xowa folders Initially, only the default user 'Labdoo' can access the post-installed Xowa wikis. To ensure that the user student also has read rights, the script set-rights-folder-files-Public-correct.sh is located on the desktop. Please execute this script every time you have installed the learning content. To do this, execute the script in the terminal or the quick version (works with this script): right mouse click on set-rights-folder-files-Public- correct.sh → Open with / Open with → Xterm (if Xterm is not offered → Open with / Open with → system tool → Xterm). The script starts without further input, runs for about 1 - 5 minutes, depending on the computer, and closes automatically.

English wikis: If the hard disk (HDD) is not large, but you still want to upload as many English Wikis as possible, go to en.wikipedia.org. (That's why the children have the Wikipedia Wikidoo filtered for children). The other English wikis together take up to10 GB, while en.wikipedia alone needs about 30 GB!

Especially for hubs in the DACH region: On request, ready Xowa wikis for frequently used languages are available in zipped form on the FTP server. Download zipped wiki → unpack it and move it into the folder /home/labdoo/Public/xowa/wiki → Set the rights of the Xowa folder correctly on the desktop using the script →.sh (see above) Have a look at hhttp://ftp.labdoo.org/download/install-disk/wiki-archive/xowa-wikis/ (in it you may find subfolders for the respective Xowa version) Maybe your language is already included. If not, send an email to [email protected].

Outlook: A Xowa version for Android mobile phones and tablet PCs is in the works. This will enable us to provide children with wikis on mobile devices in the future.

Download Xowa (for experts only) from the FTP server: http://ftp.labdoo.org/download/Public/xowa/ (but it is strongly recommended to use this installation script http://ftp.labdoo.org/download/install-disk/installskripts/installscript...). Xowa Sourceforge: https://sourceforge.net/projects/xowa/

BOKS is a set of lessons designed to help lift communities out of poverty. It involves the cumulative knowledge of doctors, nutritionists and agricultural experts who have worked among the world's poor, and pooling that information into a practical, and easy-to-use video curriculum.

We thank ISOM.org for granting Labdoo the right to freely distribute this curriculum with the Labdoo laptops. You can watch a brief introductory lesson on the video below:

You may download the zip file of the lessons to be installed in your Labdoo laptops; however, please do not distribute these lessons' material without having prior consent from ISOM.org in order to avoid violating copyright laws.

We have BOKS in 4 different languages: English, Spanish, Chinese and Swahili.

Some of the lessons include Christians' teaching to help people overcome certain physical challenges; we have added a (C) in front of those lessons. Please keep the recipient school's cultural background on the laptop and install the lessons carefully. Thank you!

Wikipedia for school is a filtered, freely available subset of Wikipedia, according to the British curriculum. Wikipedia for schools is available in English (en, release 2008 and 2013), Spanish (es), French (fr) and Portuguese (pt). The English wikipedia for schools is already part of the English RACHEL collection. Wikipedia for schools needs about 6.5GB disk space.

Wikipedia for schools occupies about 6.5GB of disk space, except for the English Release 2008 which occupies about 2.5GB.

To install Wikipedia for schools, first, download the zip into your local disk. You can download the file in the required language from the Labdoo FTP server at http://ftp.labdoo.org/download/install-disk/wiki-archive/wikis/. Open the language folder you need (e.g. EN for English) and download the archive *wikipedia_for_schools*.

Installing Wikipedia for schools on a Labdoo laptop

Once you download the file, unzip it in the folder /home/labdoo/Public/wikis (the downloading and unzipping operations could take some time depending on the speed of your network and computer). Once unzipped, double click on the file/home/labdoo/Public/wikis/xx/xx-wikipedia-for- schools/index.html (where xx is the country/language code ) to open a web browser that will take you to the initial page of wikipedia for schools.

To create access easier, we recommend making the default web browser page point to the Wikipedia for Schools' initial page. For that, open the web browser (these instructions are for Firefox but similar steps apply to other browsers) and go to File => Open File [ navigate to /home/labdoo/Public/xx/xx-wikipedia-for-schools/index.html ] => Open. Then go to Edit => Preferences [ opens a window for the settings, click on "Use current pages" and close the tab "Preferences" ]. Please repeat any of the configuration steps for both the 'Labdoo' and the 'student' user accounts that come with the Labdoo computer.

This page provides an overview of the Open Educational Resoures (OER) usually included in a Labdoo laptop. You can download all the content described below from the Labdoo FTP service: http://ftp.labdoo.org/download/install-disk/ or find it on a previously cloned Labdoo computer at /home/labdoo/Public/wikis or in the folder /home/labdoo/Public/xowa/wiki.

Links to content in several languages: English, Spanish, French, German/Deutsch, Arabic, Hindi, Bahasa Indonesian, Nepale, Portuguese, Kiswahili/Swahili.

Most educational content was taken from different sources such as KHAN Academy aswell as OER2GO project and over 800 wikis (using Xowa tool ). Please notice that except for some user manuals and video tutorials on how to use a Labdoo laptop, Labdoo images for cloning do not include any type of content. That means that after you install the Labdoo image, you have to install the educational content that suits best for your Edoovillage according to the spoken language(s), the users' age, your disk drive's size or specific demands from the teachers and students. This approach (a base image with no content plus separate installation scripts for the educational content) significantly simplifies the process of sanitizing laptops and tablets (making it scalable) and is explained in this conversation.

Of course, you can also browse through the above-mentioned website http://oer2go.org/ and download the content you need by using the tool 'rsync'. However not everybody knows how to use this tool, that is why we prepared and zipped the content in a way that is easily viewed from any browser, and we simplified the process of installing the educational content in your laptops/tablets.

Preparation

Create a folder if you haven't, according to the language(s) you need, e.g. /home/labdoo/Public/wikis/EN for English and so on Download the index-file from and into the language folder you are working on, e.g. /home/labdoo/Public/wikis/EN/index-en.html Open this index-file in a tab using the browser of your choice, e.g. Firefox, and save the tabs in its settings, so someone can open it and show it to the students at a school when starting the browser.

Download archive(s) and unzip to content folder

Download and unzip the archive(s) to the folder /Public/wikis/xx (xx = language code, e.g. EN, DE, FR, ES etc.) with the user: Labdoo. You can download the archive(s) you need by right-mouse clicking and selecting "Unpack to" Unpack and delete the archive once it is unzipped. If you run several installations please save the archives on a local server or external USB disc drive, so you do not have to download each time each file again.

Index file(s) for an easier access Labdoo prepared an index file for each language. You will find them in each language folder on our FTP server. Copy them into the local language folder on your laptop and the folder "Public".

Due to the amount of the content, you have to pre-select the content you are about to install and maybe discuss with the school or project partner which content suits best. Another option is to copy the archives to an external device and the traveler/dootripper takes it to the school, so they can decide on-site which content suits best.

Tags: 32 bit What to do with the battteries?

If a laptop battery is not in good shape, our policy is to remove the battery and recycle it before sending the laptop to a school.

There are several reasons for that:

The battery that comes with the used laptop is reaching usually the end of its life cycle. Sometimes, old batteries can cause problems to power up the laptop. The battery is one of the most poisoning waste products and we try not to pollute the environment of our schools, which may not have the capacity to properly dispose of waste. A Laptop battery adds extra weight to the laptop and this could be a limitation if the traveler who is carrying the laptop needs to travel light. Since Labdoo laptops are often used to serve in a classroom setting and many of those have power outlets, the laptops can work without the battery.

Please include only the battery in the laptop if it is still in good shape!

Tags: battery recycle How to (Physically) Clean a Laptop to Make it Look New Again

The donated used laptops often come dirty in appearance. After making sure the laptop is not broken, the next step to take is to clean the laptop case. Here's how to properly clean a laptop.

What you need: some soft clothes, a small bottle of 91% isopropyl alcohol, a box of cotton swabs.

LCD Screen LCD screens are pretty delicate, and you don't want to press hard on them, because that can burn out the pixels. Instead, grab a dry soft cloth and gently wipe the screen. If you need to, add a little bit of alcohol. In most cases, that should be all you need. Do not use anything paper- based, like paper towel, Kleenex, or toilet paper, since it can scratch up your screen.

Keyboard Clean dirty keys with a swab of rubbing alcohol to remove oil, grime, and germs. Don't forget to turn the laptop's power off before you start cleaning.

A warning note Isopropyl alcohol vapor is more dense than air and is highly flammable with a very wide combustible range. It should be kept away from heat and open flame.

Tags: clean laptop Choosing the Correct AC Adapter

Hopefully all your laptops were donated with their AC adapters. If that's the case, you can skip this section. Otherwise, this section will help you find a matching AC adapter for your laptop(s).

All laptops use Direct Current (DC) power to operate. DC is electrical energy that flows consistently in one direction. Our wall outlets use Alternating Current (AC), which varies constantly, but results in a positive flow of current. Laptops can't work on this kind of power, so an AC adapter is required to convert the wall outlet's current to DC power. Many laptops use different styles of connectors so sometimes it can be hard to find the best adapter to fit.

There are several ways to find the correct power adapter for the laptop

32 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

1. Get the laptop's model number and check online. 2. Get the power requirements for the laptop. Look for the amperage and the voltage required. You also need to compare the connector head type of power adapter with the outlet hole on the laptop. They need to match to ensure that the adapter can plug into the laptop.

Voltage (V) Voltage is the amount of potential energy between two points on a circuit which creates power to charge the laptop. If the voltage of the laptop is different from that provided by the adapter, it won't be able to create the correct charge needed to pull the electrical energy into the laptop. Finding the right voltage is also very important to keep the power from shorting out the laptop. A voltage that's too high will overload the laptop's circuits.

Amperage (A) An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. The amperage on laptop power adapters needs to match or exceed the amperage required by the laptop.

Tags: troubleshooting Packaging the Laptops Ready for Traveling

Packaging the laptops ready for traveling

Once a laptop has been sanitized, we need to package it so it can travel to a destination school. The main goals of the packaging are two-fold: (1) the packaging should protect the laptop from any possible rough traveling conditions; (2) the packaging should make visible the Labdoo identifier of the laptop, for both its AC adapter and the laptop itself. A recommended approach is to use transparent, bubble plastic wrap and to tape the Labdoo identifier in big letters outside, for both the laptop and its AC adapter, as shown in the following pictures:

Figure. A good way to pack your dootronics: use a wrapping material to properly protect them and write the Labdoo IDs clearly outside both the devices and the AC adapters.

You are welcome to use other packaging approaches based on what's available to you, as long as the laptop is well protected and its Labdoo identifier is made visible externally. List of Countries Voltages and Power Plugs

Different countries have different power plugs and voltages. One good news is that practically all (if not all) portable computers (laptops, tablets, etc.) accept all voltage inputs. So the only adapter that we need to consider when contributing a dootronic is the power plug needed in the destination school. Unlike voltage adapters, power plugs are just mechanical, and so they are very inexpensive (between $1 and $3 typically). Because it is difficult to tell where each dootronic will be destined, the general rule is that the responsibility to acquire the power plugs falls under the recipient school and the NGO or organization which is supporting it.

In the following list you will encounter the specifications of the power plugs and voltages for each country.

If you are not able to find a solution to your problem in this section, please ask your questions to the Labdoo QA team and another Labdooer there will provide an answer for you. Delete All Data on Hard Disk

We want to ensure all data stored in every donated computer is properly erased before installing the new operating system. Therefore learning how to properly erase the hard drive is the first step in the laptop sanitation process.

You have 2 options to completely wipe out all previously stored information in the computer (user information as well as all the previously installed softwares and operating system)

Method1: Using Lubuntu disk

1. Boot your laptop with your Lubuntu disk (see the simple sanitation guide to learn how to create a Lubuntu disk) 2. On the Lubuntu menu, select the option 'Try Lubuntu'. This will start Lubuntu on the laptop. 3. Once booted, press at the same time the keys ALT+CTRL+F3. This will take you to a terminal console. 4. In the terminal console, type the following command to ensure that the shred application is available:

apt-get install coreutils

(you need to have your laptop connected to the Internet for the above command to succeed)

5. Now type the next command:

sudo shred /dev/sda -f -v --iterations=2

If this command does not work, you can try with 'hda' instead of 'sda', like this: sudo shred /dev/hda -f -v --iterations=2.

6. Now wait for about an hour or so for the previous command to complete. At the end of this process, the laptop hard drive will have all of its previous data fully removed. You can now press ALT+CTRL+F7 to return back to the Lubuntu initial screen and turn off the laptop.

Method 2: Using Parted Magic or Labtix disk

1. Boot your laptop with Parted Magic disk (see Advanced Method(Without Network) to learn how to create a Parted Magic disk)

Or you can boot your laptop with the Labtix disk (see Preparation for the Fast Installation Methods to learn how to create a Labtix disk)

2. Once booted, click on the bottom ROXT Terminal (xterm icon on the lower right) This will take you to a terminal console.

3. In the terminal console, type the following command to ensure that the shred application is available: sudo shred /dev/sda -f -v --iterations=2

If this command does not work, you can try with 'hda' instead of 'sda', like this: sudo shred /dev/hda -f -v --iterations=2.

4. Now wait for about an hour or so for the previous command to complete. At the end of this process, the laptop hard drive will have all of its previous data fully removed. You can now shutdown the laptop from Parted Magic window.

Tags: sanitation Adapt Bluetooth's Name (Optional)

If you sanitized your laptop via the advanced method, then due to the cloning process, the name of the laptop's bluethooth device will be identical to all clones. To assign a unique name to your device, run the following command on a terminal:

sudo hciconfig hci0 name ’labdoo-XYZ-0'

Where XYZ is the Labdoo ID of the laptop. Add a 2nd Disk Drive

If the installed hard disk becomes too small and the computer allows the installation of a 2nd disk, you can configure such 2nd disk to mount automatically during booting time. To do so you have to:

Press ALT+CTRL+T at the same time to start a terminal, and type the following command to initiate the file manager in superuser mode: sudo pcmanfm & (enter). Navigate to the folder /mnt and create inside it a new folder with the name of the 2nd disk. Get the UUID (ID of the disk-drive) of the 2nd disk by typing the command sudo blkid, search for your 2nd drive in the list and write down its UUID. Type the following command to edit the fstab file: sudo nano /etc/fstab [Enter] Add at the end of the fstab file a new line as follows (in one single line): UUID=[add here the UUID of the 2nd disk you wrote down above] /mnt/[add here the name of the 2nd disk folder you created above] auto defaults 0 0 (Make sure to leave a space character between each entry) Leave the file editor by pressing CTRL+X then Y (to save) and [Enter]. Optionally, to allow access for all users to your 2nd disk do as follows: Open your file manager in superuser mode again sudo pcmanfm &, go to your 2nd disk folder and right click on it with your mouse. Under properties, select "Access rights for others", check the "Allow create or delete new files / folders", and then "Apply to all folders".

Re-boot your computer. The new disk should be automatically mounted. Add a Local Printer as Network Printer

If you have a printer directly connected to your Labdoo computer (via USB or a Centronics cable), you can share access to the printer from other computers via a local network. To do so you need to use CUPS (Common Unix Printing System) as follows.

Configuring the Labdoo computer attached to the printer:

34 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Open the web browser and type the URL address http://localhost:631 On the admin page http://localhost:631/admin/ select “Share printers connected to this system”. Select under ”Printers” the connected printer. Click on the menu “Administration” and on “Printer”. Leave “Actual connection” unchanged → Proceed → select “Allow access to this printer / share”. Optional: add a name for the place of installation → Proceed → Change settings.

Showing the printer on other Labdoo computers connected via the network:

Open the web browser and type the URL address http://localhost:631/admin Select the option “Show printers shared by other systems” → Change settings.

After this you should see the printer in the menu “Printer". Maybe you have to wait a little bit before the printer is shown or re-load the page http://localhost:631/admin/. Configuring the Bios

How to change the booting order of a laptop from the bios

BIOS (Basic Input Output Subsystem) is a programmable chip that controls how information is passed to various devices in the computer system. A typical method to access the BIOS settings screen is to press ESC, F1, F2, F8 or F10 right after you start your computer.

BIOS settings allow you to run a boot sequence from a hard drive, a CD-ROM drive, the network, or an external device. You may configure the order that your computer searches these physical devices for the boot sequence.

The first device in the order list has the first boot priority. To install the Labdoo software you will need to ensure the CD-ROM, the USB or the network (depending on which method you use to install the software) are given the highest booting priority.

Note: in the case of a USB installation, before you set boot priority for the USB device, plug the device into a USB port to ensure the BIOS will be able to detect it.

To specify the boot sequence:

1. Start the computer and press ESC, F1, F2, F8 or F10 (depending on the BIOS manufacturer, try them all if needed) multiple times during the initial startup screen. A menu may appear. 2. Choose to enter BIOS setup. The BIOS setup utility page appears. 3. Use the arrow keys to select the BOOT tab. System devices appear in order of priority. 4. To give the CD/DVD, the USB or the Network the highest boot sequence priority, move such device to the first position in the list. 5. Save and exit the BIOS setup utility. 6. The computer will restart and will initiate its booting process by looking first at the device you gave the highest priority, allowing you to install the Labdoo software.

Figure. Illustration of the BIOS boot menu where you can change the booting order.

Troubleshooting potential issues with the bios.

In some rare cases the BIOS could be reset during the process of deleting the hard drive information from the system, or some times older laptops do not support internal and/or external USB keyboards during the booting process. It might happen that you are not able to use the arrow keys (up, down, right, left) to configure the BIOS. In such cases the USB control (and sometimes the internal keyboard) was deactivated. A possible solution is to connect an external PS/2 or USB keyboard, and continue to install or adjust the BIOS. DKMS (Automatically Driver Updates)

Dynamic Kernel Module Support (DKMS) is a program/framework that enables generating Linux kernel modules whose sources generally reside outside the kernel source tree. The concept is to have DKMS modules automatically rebuilt when a new kernel is installed.

An essential feature of DKMS is that it automatically recompiles all DKMS modules if a new kernel version is installed. This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade.

To install DKMS, do as follows:

35 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

- Open a terminal by pressing at the same time the keys ALT + CTRL T - Type in the following command: sudo apt-get install build-essential dkms [Enter] + [Password] + [Enter]

Note: DKMS is already installed if you cloned a laptop using the advanced method or if you used the installscript-software.sh. Firefox shows black bar in URL

In combination with an Intel graphic card Firefox shows sometimes in the URL line a black bar. There is nor solution for that, just a workaround:

If there is nor entry gfx.xrender.enabled (double check that you did not mistype!):

click in the white space of the search entry Select New in the dialogue window In the next windows select boolean In 3rd window select false and confirm with ok

Restart Firefox

Tags: firefox Check for Disk Errors with GSMART

To check whether a disk has potentially any errors, you can use the Lubuntu tool GSMART. Since it is not installed by default, it must be installed via the Ubuntu Software Center. Select GSMART and install it. After installation, start it and initiate a check. This software includes a quick check (about 10-20 minutes) or a detailed check (about 30 - 60 minutes).

In case you want to check multiple disks, you can use a hard disk adapter. The adapter should support IDE and/or SATA via a USB connection to your laptop. Installation of Restricted Codecs

Please notice that the usage of restricted codecs might depend on local laws. It might be illegal in some countries to install and use certain codecs (commercial/proprietary third-party packages) and multimedia extensions. Check your local regulations first prior to proceeding with the installation of the following software.

As in all software for Ubuntu, there are two ways to do the installation: via the Ubuntu Sofware Center or via the command line.

The installation via the Ubuntu Software Center is as follows. Open the Ubuntu Software Center (or the Synaptic Package Manager) and search for "restricted codecs". Select the package found and click on install. During the installation you will need to accept an EULA license agreement. To have full support to watch DVDs you must also install libdvdcss2 and non-free-codecs from the Medibuntu Repository. Please notice that in Europe these repositories are not allowed to be used. Further information can be read here: http://www.videolan.org/developers /libdvdcss.html

The same installation can be done via the command line through the following steps. Open a terminal by pressing at the same time the keys ALT+CTRL+T. Then type the following commands:

sudo apt-get install ubuntu-restricted-extras -y (Enter) sudo apt-get install non-free-codecs -y (Enter) sudo apt-get install curl -y (Enter) curl ftp://ftp.videolan.org/pub/debian/videolan-apt.asc | (Enter) sudo apt-key add -echo "deb ftp://ftp.videolan.org/pub/debian/stable ./" | (Enter) sudo tee /etc/apt/sources.list.d/libdvdcss.list (Enter) sudo apt-get update (Enter)

If you have a computer with an Intel graphical interface, there is a cool free tool by Intel Graphics for Linux that you can install, check it out: https://01.org/linuxgraphics/

To install it do as follows:

Open Firefox and go to https://01.org/linuxgraphics/downloads Depending on the Ubuntu release (version 32 or 64 bits) download the matching software and install it. Once installed, find the newly installed application and run it. It will guide you through the process of configuring your system for Intel Graphics. Once done, you will need to restart your computer to load the new configuration. Kernel Panic Caused by Defective in Memory/RAM

If the computer crashes often during the boot process, there is a possibility that it is because of a defective memory (RAM) module. (There could be other reasons too naturally).

36 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

To check if the RAM module is working properly (memory modules) do as follows:

Boot the system and press SHIFT at the same time. The GRUB menu will show up. Click on Memtest86 (memory test). The system will perform a memory test. At the end of this test, the defective parts (if any) will be listed and marked in red.

Hint: To know exactly which memory module is defective, you can remove all memory modules and check each of them individually by running the above test. Wired LAN Interface is Not Working

In some systems, the wired (cable) LAN interface may not be recognized. The symptom is that the interface shows up when you click on the network manager icon but it shows as deactivated. To get it to work, try the following:

Open a terminal by pressing ALT+CTRL+T and type the following command: sudo nano /etc/NetworkManager/NetworkManager.conf Check and change this line: managed=false → managed=true Save the file and restart the network manager: sudo service network-manager restart LXDE - Create a link to folders or files

To create a symbolic link:

Using the file manager. Open file manager PCMan, click on the folder or file, press CTRL+SHIFT and click on the folder/file at the same time, then drag and move it to the desktop or the location where you want to create the symbolic link.

Using a terminal. Open a terminal by pressing ALT+CTRL+T and type:

ln -s -t [path to location where you want to create the link] [folder or file that you want to link] (Enter)

For example: ln -s -t /home/labdoo/Desktop /home/labdoo/Public/videos

MD5 is a common way to calculate checksums to test if a file was downloaded correctly. You can read more about MD5 here http://en.wikipedia.org/wiki/MD5.

In the folders of your unzipped Labdoo images for cloning you will find a file MD5SUM. Use these files to check if the downloaded images are healthy and not corrupted by the download process as follows.

Check that the downloaded images are correct:

Open a Lubuntu terminal Navigate to the folder where the files are located cd ...(path) [enter] Execute the commandmd5sum -c MD5SUM [enter]

Open a terminal in the folder with the files and execute in a terminal md5sum * > MD5SUM (Enter) 16.04 LTS does not boot, graphic resolution on screen low

Grub 2 (GNU GRand Unified Bootloader 2. Generation) is the tool that rules the Boot order in the Linux Machines

We try to give here some tips on the different problems you may have with it. You can find an overview under https://help.ubuntu.com /community/Grub2 and its configuration possibilities under https://help.ubuntu.com/community/Grub2/Setup#Configuring_GRUB_2

We will describe here some of the possible problems you might experience when you boot (L)Ubuntu 16.04 LTS for the first time. Some laptops do not boot up properly, but instead "hang", or they can have a wrong, too low, graphic resolution, or they may go straight off at startup, or hang with a black screen. These problems can often be resolved by setting in the Grub configuration file.

If a laptop gives you too much trouble, contact a Labdoo Hub and its helpers.

Start computer using the "Recovery Mode" as follows:

Keep the Shift-button pressed when turning laptop on, press again after the BIOS messages shown, until the Grub menu is shown (GRUB controls the start process). You will also see the GRUB menu if power (I/O) is turned off during a start process. Select "advanced options" and a Linux-Kernel and "Recovery-Start", just accept the next entries (press Enter) and log-in as labdoo user. Alternatively, press the "e" key when the Grub Select menu appears. This change only applies to this boot process and does not replace the Grub2 configuration file for next boot processes (so that the configuration file needs to be modifed).

Changes in the grub2 configuration file

After booting and logging in, open an editor like nano , eafpad or vi. In this document, the further steps are based on the use of the nano-editor. Open a terminal and type sudo nano /etc/default/grub (Enter). This will open the GRUB configuration file. If you are not familiar with the nano editor can use leafpad instead sudo leafpad /etc/default/grub (Enter) After you have done the desired changes in the configuration file, save it and end editor (using nano editor by typing STRG/CTL and the letter o, then press Enter, next type STRG/CTL and x) Then open a terminal and type sudo update-grub (Enter). This will finally store the changes made within the GRUB configuration. Reboot computer. Hopefully the new configuration allows you to get the login screen correctly displayed

TYPICAL PROBLEMS YOU MAY FIND AND THEIR SOLUTIONS

Computer does not boot or graphical resolution is wrong

37 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

If the graphical resolution is wrong (usually too low), try:

Edit the grub config file as described above

Search the line # GRUB_GFXMODE=640x480 and remove "#" at the beginning of the line (this "#" symbol disables the configuration described in that line, by removing the '#' you are now configuring a determined resolution). Change the pre-set resolution of "640x480" in the setting you need for the graphic resolution. Important: you may only use a resolution supported by your video card! You can get the possible resolution(s) as follows using the (L)Ubuntu desktop or Parted Magic:

(L)Ubuntu Desktop: Menu, select Preferences → Outputs → default → Resolution : will show available settings for resolution Parted Magic: Menu → Desktop Settings → Screen Layout Editor → Outputs : will show available settings for resolution OR System Profiler → Display → Resolution Store the modification and end editor. Then open a terminal and type sudo update-grub (Enter). This will finally store the changes made within the GRUB configuration.

Having made these changes you have a good chance to start your laptops using (L)Ubuntu 16.04 LTS, showing a good resolution on screen.

Tags: tips ubuntu 20.04 Change keyboard layout when logging in (Boot)

The Image for Cloning "remembers" the keyboard layout of the computer, on which the image was generated. Usually Images are produced on computers having a German keyboard - sorry for that :( When you start a computer with a different keyboard layout you might have a problem to log-in properly. You are able to change the keyboard layout for each user after logging in. But that will not solve the problem. First you have to log-in and next you have to change a system setting.

Here is the layout of a German keyboard so you should be able to find the letters labdoo (our standard password to log-in). After logging in you should change the keyboard layout first and next change the keyboard system setting.

For LXDE/MATE and Log-in (Light-DM)

Having booted you are able to log-in. The computer will get the keyboard layout of the file /etc/default/keyboard. You change it as follows:

Open a terminal, type sudo nano /etc/default/keyboard and press (Enter)

38 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

in the terminal window search for the line XKBLAYOUT="de" change de to the keyboard layout you need e.g. en, fr etc. optional: Changing the next line XKBVARIANT="" you can add a country specific keyboard layout (e.g. "ch" für eine deutsch-schweizer Tastatur de-ch or a special Spanish variant etc.) Save modified file (Ctl/Strg + O (enter), close terminal by pressing Ctl/Strg + X)

Important: The keyboard layout for the users labdoo or student will not be changed by this setting. After logging in you can change the user keyboard as described here https://www.labdoo.org/content/post-installation-configuration.

Tags: layout keyboard boot log-in Monitor is only showing a small part of the full screen

The installation process was successful and you are able to boot, but when logging in you are only able to see a part of the screen (usually the upper right screen corner) with a poor resolution.

This could be because in the BIOS setting not enough RAM was allocated for the screen memory, e.g. 1 MB instead of 8 MB or more. Please check the bios and increase the memory allocated for the screen memory if necessary. Samba / Windows Server

Starting from April 2018 and with the 18.04 LTS (L)Ubuntu release, a Samba server comes pre-installed on image cloned laptops. This means that a Labdoo laptop can be used as a server to other computer clients allowing these clients to access all the educational content in the server. This is a powerful configuration as it allows many types of devices (laptops, tablets, mobile phones, etc.) to access the educational content in the server without the need to have access to the Internet or the need to replicate the educational software in many devices.

Due to the speed of the server or the network, there are limitations in the number of computer clients that can be supported by one computer server. If too many clients are connected, the performance of the data transfer will become slow. So if you have many computer clients, it may be necessary to have more than one computer server.

This page describes how you can convert a Labdoo laptop into your own computer server to provide access to other computer clients. With a few simple steps a server can be set-up, check out the next instructions on how to do that!

Install Samba server

1. Install the package "samba" by running in a terminal sudo apt-get install samba or via the Linux package manager, e.g. synaptic. 2. Type smbd [Enter] in a terminal to start the Samba server manually. To avoid starting this program each time manually, you can add "smbd" as a command in menu → Preferences / Settings → Personal / Personal → StartUp Applicatons / Start Programs → with "Add" → Name: Samba / command: smbd / Comment: add start up of Samba Server.. This will start the Samba server every time you reboot the system. 3. If necessary, install additional extensions to the system's file managers to bring a better use experience. For instance you can install "caja-share" by typing in a terminal sudo apt-get install caja-share or by using the synaptic package manager (this extension is also part of the Labdoo Image since April 2018).

Set up the Shared Folders

1. Open Caja as administrator/root by running sudo caja [Enter] in a terminal and right click on the folder you want to share. Click in the context menu "Share". Please notice that if Caja is not started as root, the menu item "Sharing" will not appear. 2. Activate "Share this folder" and "Guest access", then enter your own "Share name". 3. Close Caja. 4. Alternatively for LXDE Desktop, install instead the File Manager PCManFM: Go → network → usually then the server is already recognized and displayed, otherwise Windows network → Workgroup → Server name select, usually labdoo-00000xxxx where xxxx is the Labdoo ID of the computer. 5. Finally, don't forget that the computer must be connected to the network via LAN cable or WiFi.

Access to the server via tablet, mobile phone, laptop or PC clients

Depending on your client and operating system installed and in use (Android, iOS, Windows, Linux etc.) access to the server may be different. Below you will find some examples and tips. There are also useful programs such as file managers, browsers, pdf viewers or ebook readers on your device. Check if your file manager is able to connect to a server (not all apps are able to) or if additional extensions need to be installed.

Access to the Server Using a Client

In a (L)Ubuntu officially cloned Labdoo laptop comes with the file manager Caja. Either use the Menu → Places or use Caja and in the left column go to "Browse the Network" to scan and show all the servers in the network. Android - open your file manager and click on "network". The network will be scanned for SMB-shares which will be shown in a file manager. If your installed file manager is not able to handle SMB, you have to install one with this ability. We recommend the file managers Ghost-Commander (to be installed using the apps store Google Play: both Ghost Commander and Ghost Commander - Samba Plugin need to be installed) or the X-plore add on. iOS (Work in Progress) Windows (Work in Progress) To open the "Public" shared folder just double-click it. Then confirm "Connect as anonymous" to get connected. For a faster experience, nearly all operating systems and file managers offer a way to bookmark favorite folders. Use it to bookmark the access to the server.

Connecting to the Server Using Ghost Commander in Android

The example Ghost Commander is similar to other file managers.

1. Start Ghost Commander. 2. Open "home" directory (arrow with dot right upper corner). 3. Click on "Windows shares". 4. In the window "Connect to Windows PC" click on "Search". No further input should be needed to connect to the server. 5. Click on "Workgroup". 6. Click on the name of the server you want to connect to.

39 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

7. The shares of the server should be listed in your file manager.

To create a Bookmark Using Ghost Commander

1. Click and hold on for about 2 seconds on the share you want to bookmark until a context menu opens. 2. Click on the context menu "NAME_OF_THE_FOLDER as favorite". 3. Now you will see the share at /Home (Arrow and dot upper right corner) /Favorites and have direct access, provided the SMB server is online and connected to the local network.

Note: Some file managers first store documents and pages locally before opening and displaying them. This can end up filling up the memory in your device. Cleaning up the memory can help.

Display Educational Content and Documents

Off-line web content: can be shown in your client's browser. Local off-line content must be stored using relative links (not absolute links). pdf: to be displayed and read using a PDF viewer. Office documents: It does not matter if you want to open and read Microsoft Office, LibreOffice, OpenOffice documents etc. in all these cases a viewer software app must be installed which can handle the file content. Video / audio files: In this case the client must also have matching software / apps installed to watch videos or to listen to audio files.

Make Xowa Accessible from other Devices

Xowa comes with an http-server to help share Xowa wikis within a local network. Navigate to the folder /home/labdoo/Public/xowa and open a terminal (e.g. using the file manager Caja: File →open a terminal here). Run the Xowa-jar file in this folder as follows:

For 64 Bit installations: java -jar xowa_linux_64.jar --app_mode http_server [Enter] For 32 Bit installations: java -jar xowa_linux.jar --app_mode http_server [Enter]

Don't close this terminal window, as otherwise the Xowa process will be stopped. So leave it open as long as Xowa is used by other client devices.

Some devices, operating systems and browsers can resolve the hostname into its IP address. The IP address is like the address number of a home, which controls the access to each device inside your LAN (Local Area Network).

If the IP address cannot be resolved automatically you can get it manually. From the server computer, first right mouse click on the network/WiFi symbol on the desktop → Connection Information → read IP address (often similar to 192.168.1.xxx). Notice: The IP address will change every time, when you reboot the server (if you run DHCP for dynamic IPs in your network). It might be helpful to assign a static IP address to your server.

Read Xowa Content on any Client

The following is based on the IP address 192.168.1.133 just to illustrate an example. Instead of this IP address, use your server's IP address. Open the browser of your choice on your device (tablet, mobile phone, PC) and type the address of the server: SERVER_IP_ADDRESS:8080 In our example: 192.168.1.133:8080:8080

Tags: samba server windows handle share android ios tablet mobile phone device Using a Laptop as WiFi Hotspot to provide educational data to mobile devices

Introduction If a Labdoo laptop is member of a LAN or WiFi network, it can provide data (educational content) to other devices of that network, e.g. to mobile phones or tablets. This can be done either by some network share – e.g. via samba (smb) or e.g. via a web server (e.g. Apache web server). In both cases, educational content on that laptop could be accessed by other mobile devices (mobile phones, tablets) via their web browser. This might be a reasonable use case if these mobile devices do not contain Labdoo educational content (e.g. due to having not enough disc space for this content)or no having internet connection. In the case of a WiFi connection, we commonly assume that our laptop is connected to a WiFi router, to which all other mobile devices are connected.

40 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

But what do we do if no WiFi router is available? If a WiFi USB-adapter or a built-in Wifi is available on it, is possible to use a laptop as hotspot and host a WiFi network. There a 2 options - use a Samba (smb) file server, which offers a Windows-compatible server (easy to start and handle). Or you can use Apache server, which is bringing a full web server to a laptop (more complex), being able to spread content and web- sites locally and world-wide (if connected to internet). Such a setup is outline in this document.

using Samba (smb) server

using Apache web server

Target Group The target groups are Labdoo schools, which do not have a running WiFi network, but need a network to provide file, content and/or Internet access to other mobile devices. Example: The Labdoo school have tablets or smartphones, but no Labdoo content on them.

Then the school is able to use a Labdoo laptop as server and spread the educational content to mobile devices. The number of mobile devices to be provided by one laptop depends on its capacity, mainly speed of CPU, disc and WiFi connector. In our tests we found 3 - 10 devices a reasonable number of clients to be connected to one laptop.

Each Labdoo laptop comes with a preinstalled Samba server (smb). How to start the smb-server and how to connect mobile devices to it is

41 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

explained here.

You will find most content on each laptop in the folder /home/labdoo/Public/wikis. Navigate in a browser of your mobile device to the sub- folder (language) needed. Search for the start file, in most cases index.html, start-here.html or similar. Then you can read and use links etc. on your mobile device as reading on a laptop.

Technical Aspects Most modern smartphones can be used to host a WiFi network. However, not all WiFi chips of laptops or USB-sticks (and their drivers) support this feature. According to the Ubuntu Users Wiki [1], these WiFi chips do the job: • chips driven by the hostap driver or • chips working with a current mac80211/nl80211 sub-system A detailed description on how to set up the laptop as a WiFi hotspot is given in the Ubuntu Users Wiki [1]. The procedure works with (L)Ubuntu 14.04 - 18.04 LTS. • provide files access (e.g. via Samba, offering Windows-compatible file services) and / or • run a webserver to provide browser based access on educational content (e.g. via Apache) • share its Internet connection (e.g. if the Laptop has WWAN) to mobile devices connected to the WiFi.

Tags: wifi laptop server mobile devices tablet samba web server Windows look-alike user interface

For the explained reasons and advantages, Labdoo uses the Linux operating system. However, some users prefer a graphical user interface (GUI) which looks like Windows so that the learning curve for some users is even lower. In this page you will find a guide on how to install and configure the Lubuntu GUI to look similar to Windows.

Those using Labdoo Images for Cloning can stop reading here, as the images are coming with pre-installed Windows 10 themes and icons that can be activated.

Installation

Windows 10-look alike user interface might be for instance downloaded from here https://b00merang.weebly.com/windows-10.html or from https://github.com/B00merang-Project/Windows-10 (download light and dark theme, icon set)

Unpack the archive and move the files using superuser rights to these two folders (you can open a terminal with ALT+CTRL+T and then type sudo pcmanfm [enter] to open a file browser from where you can move the files):

Move themes to /usr/share/themes Move icons to /usr/share/icons

Check the rights to access and update them, if needed (right click on the file, and select Properties → Permissions → View = anyone; change = only owner; Access = anyone).

Activate

In order to activate the new themes, click on the Lubuntu-start button on the left bottom corner of the screen and select Preferences → Customize Look and Feel → select in the tab widget the Windows theme → click on the icon theme and select Winx-x.x.x → close the window.

To undo / switch back to the default Linux theme just select another theme (Lubuntu-default) and icon theme (Lubuntu) or other layouts that you may like.

The tool to be installed is named NTP – Network Time Protocol (open a terminal: sudo apt-get install ntp → Enter or alternativ via the software center) for Network Time Protocol.

You don't have to adjust anything else. The time is taken from web server. You are able to define time zone and server. Online access is needed.

NTP is already part of the Labdoo images and install scripts. NVIDIA grafical drivers, problems and solutions

1. If a computer is not able to boot and if you are not able to log-in sometimes you are still able to have access via terminal:

Either using CTL+ALT+t (if logged in), CTL+Alt+F3 or follow the GRUB information using the recovery mode: sudo apt-get purge nvidia-current (Enter) sudo apt-get install linux-headers-generic (Enter)

42 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Reboot.

2. Preferences --> Additional Drivers --> wait a while and if proprietary drivers are offered for downlaod. 3. NVIDIA driversfrom PPA (source) of developer community

Herefor you have to add an additional source for software (PPA). Please be aware of potential risks of adding sources (PPA) to your computer:

CTL + ALT + F3 (in recovery mode) or CTL + Alt + t if logged-in opens terminal

log-in as user labdoo and password labdoo, sudo su (enter) + Passwort labdoo eingeben (enter)

To add PPA for Ubuntu 14.04 / 13.10 / 13.04 / 12.10 sudo apt-add-repository ppa:xorg-edgers/ppa (enter)

To add PPA for Ubuntu 12.04 / 11.10 / 11.04 / 10.04 sudo apt-add-repository ppa:ubuntu-x-swat/x-updates (enter)

and: sudo apt-get update (enter) sudo apt-get install nvidia-current nvidia-settings (enter) sudo reboot (enter), um Laptop neu zu starten.

4. If your computer is older (built before 2004) it does not make sense as this card is not supported anymore. It is worth a try to use either Lubuntu 12.04 LTS or to use the Labdoo Image for cloning for Lubuntu 12.04 LTS. Open a terminal

Often you will read "open a terminal". Here is explained how to do so:

Either press at the same time the 3 keys CTL + Alt + t.

Or alternatively → System tools → click on UXterm or XTerm

The terminal window will be shown.

At the beginning of each line you can read name of the user @ name of the laptop, e.g. labdoo@labdoo-000004xxx. You are now able to type in your comands.

When executing a command line wait until you see again this beginning of a line.

To close a terminal either type “exit” → Enter eingeben, when the command is proceeded.

During the installation process of Lubuntu or during the boot process you are able to press CTL + Alt + F3 and you get access to the terminal level. Using CTL + Alt + F7 you get back. Remove former Linux kernel releases

If you update to newer linux kernels the old kernels stay on the disc. Each kernel need about 60 - 140 MB. To remove them you have to open a terminal:

To rmeove former Linux kernels execute in a terminal:

sudo dpkg -l | grep linux-image (Enter)

The result should look like

ii linux-image-3.2.0-31-generic 3.2.0-31.50 Linux kernel image for version 3.2.0 on 64 bit x86 SMP ii linux-image-3.2.0-32-generic 3.2.0-32.51 Linux kernel image for version 3.2.0 on 64 bit x86 SMP ii linux-image-3.2.0-33-generic 3.2.0-33.52 Linux kernel image for version 3.2.0 on 64 bit x86 SMP ii linux-image-generic 3.2.0.33.36

In this example you might delete the kernels 3.2.0-31 and 3.2.0-32 (the numbers might differ from your list, please exchange). The last 2 kernels with the higher release numbers shoud remain:

sudo apt-get remove --purge linux-image-3.2.0-31-generic (Enter) Search files in all folders and delete them (optional)

Open a terminal (CTL + Alt + t) and execute

only to search and list: find ./ -type f name „Dateiname“ (Enter)

search and delete: find ./ -type f name „Dateiname“ -delete (Enter) (Be careful!!!) Installation of VirtualBox

When you are installing VirtualBox the first time manually please follow these steps (if you are cloning you can ignore this wiki page):

You can easily install Virtualbox a tool to run Windows or other opertaing systems as guest in a window; min. 2 GB RAM and Dual Core CPU recommended. You also need a license of the Operative System you want to install!) Just follow the instructions described under https://tecadmin.net/install-oracle-virtualbox-on-ubuntu/ more information and steps are explained in the wiki VirtualBox in Ubuntu documentation

After having installed VirtualBox you have to add the matching Extension Pack. Important: Please make sure that the release number of VirtualBox and Extension Pack are identical! For this purpose, start VirtualBox (either using the icon on the bottom left Lubuntu --> Run --> virtualbox (Enter) or by Accessories --> VirtualBox) and open Help --> About VirtualBox to see the release-no. of VirtualBox. Next step is to

43 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

open File --> Preferences --> Extensions to see the release-no. of the Oracle VM VitualBox Extension Pack. Both must match, if not please follow the steps explained below.

Update, Update to a higher VitualBox release number

If the VirtualBox is only patched without upgrading to a higher version no further actions have to be taken. In longer intervals the (L)Ubuntu distribution upgrades VirtualBox to a higher version number. In such a case, the Extension Pack will not automatically be updated. For this purpose, proceed as follows:

To Update the Extension Pack First check the release number of the installed Virtualbox version →Help → About VirtualBox → you can read the version no. in the window in the format x.x.xx (e.g.. 5.1.34). For LTS releases of (L)Ubuntu often older versions are used due to reliability. Next open in VirtualBox menu File→Preferences→Extensions and remove the former Extension Pack (mark it and click on the blue square with the red X) Then download the matching Extension Pack from the homepage https://www.virtualbox.org/wiki/Downloads. If you are not able to find the installed your version no. on this page, scroll down to VirtualBox Older builts. Click here and search in the next pages the matching release no. Extension Pack All Platforms → "Open with VirtualBox", and follow the steps to install it, ready.

Tags: installation virtualbox WiFi cards will not be detected

1. Initial Considerations.

Before you check for the cause of a non-functioning wireless card (WiFi) please check that:

The wireless LAN (WiFi) function is properly activated via the hardware switch/slider (often on one side of the laptop) or via a function key on the computer keyboard, There is a wireless card (WiFi) installed (often we get laptop donations without a wireless card), see below Check which WiFi chip is installed and check the manufacturer name. In case there is no WiFi card installed you can add one or use a connection via LAN (cable).

Sometimes older or very new WiFi Cards are not recognized automatically. The following check list provides a set of steps that you can try to fix this situation.

2. Check list.

Check if specific drivers are needed

Preferences → Software & Updates → Additional Drivers → wait a while → either "no additional drivers available" is hown → no further action should be needed, or → a list of availble drivers is shown → click the driver you want to use → Apply Changes

Check which WiFi chip is installed and check the manufacturer name

Open a terminal and execute: lspci | grep -i net (enter) or to show chip set and manufacturer: lspci -nnk | grep -i net -A2 (enter) or in case of using an USB Wifi stick: lsusb (enter) Note: Some build-in WiFi cards are recognized as an external USB, so if in doubt try also these commands.

To check if your WiFi card is supported: https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported http://linux-wless.passys.nl/ https://wireless.wiki.kernel.org/en/users/drivers http://wiki.ubuntuusers.de/WLAN/Karten http://wiki.ubuntuusers.de/Systeminformationen_ermitteln?redirect=no#Har...

Check if the Broadcom WiFi chip is not detected

If your WiFi card is based on the Broadcom chip set you are able to install: sudo apt-get update (enter) sudo apt-get install firmware-b43-installer (enter)

After rebooting the system it should work. If not activate the driver by hand: sudo modprobe -r b43 bcma (enter)

Try installing Linux Backport Modules

Linux Backport Modules can be installed to get support for many older Wifi cards. The Backport Modules are already part of Labdoo Image for Cloning and installscript-software.sh.

A detailed list of the supported WiFi cards can be found here: http://wiki.ubuntuusers.de/WLAN/Linux-backports-modules https://wireless.wiki.kernel.org/en/users/drivers

To install execute in a terminal: for Lubuntu 12.04: sudo apt-get install linux-backports-modules-cw-3.6-$(uname -r) (Enter) for Lubuntu 10.04: sudo apt-get install linux-backports-modules-wireless-$(uname -r) (Enter) and for all Lubuntu versions: sudo apt-get install linux-firmware-nonfree (Enter)

If it does not work you can try:

Try installing NdisWrapper

Details at: http://wiki.ubuntuusers.de/WLAN/NdisWrapper

44 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Please check, if

the 32 Bit or 64 Bit driver of the WiFi card matches with your Lubuntu version (32 or 64 Bit) the .inf file of the driver is enclosed, e.g. Intel encloses .inf only in the .zip version, not enclosed in the .exe!

Follow the instruction in the upper Wiki (please add here an English Wiki link).

If this does not work try:

Try installing the native WiFi driver of the manufacturer.

Please search in web for more information.

Tags: wifi drivers driver card acer - special keys are not detected

Some acer laptops (and Medion in Germany) have special keys e.g. to activate WiFi, but these keys are not detected.

From Linux kernel 3.2 or Lubuntu 12.04 there is a core module wistron_btns, offering the same functionality as before acerhk (not needed anymore).

wistron_btns has the advantage that it is part of the kernel. So installing and compiling is not needed. And 64 Bit systems are supported as well.

To use and activate open a terminal and execute: sudo modprobe -v wistron_btns (enter)

Taken from: http://wiki.ubuntuusers.de/Acer_Hotkeys apt-offline - update computer offline

There is the tool apt-offline. You can download an update at a place, where you have access to internet, e.g. at home. apt-offline allows you to easily upgrade or install new packages on your offline PC, by using another online PC.

To Install apt-offline (execute in a terminal, press ENTER): sudo apt-get install apt-offline (Enter)

Upgrading: On the offline PC: sudo apt-offline set /tmp/apt-offline.sig On the online PC: sudo apt-offline get C:\apt-offline.sig --bug-reports --threads 5 On the offline PC: sudo apt-offline install /media/USB/apt-offline.zip

Note: the following is only needed for Lubuntu 12.04 LTS, since in lubuntu 14.04 LTS keyboard layout switching works well without this.

In version 12.04, Lubuntu / LXDE comes without no tool to switch keyboard layout. With the tool lxkeymap it can be solved easily.

To install lxkeymap open a terminal [ALT+CTRL+T] and execute the following command:

sudo apt-get install lxkeymap [Enter]

Open in menu "settings" -> Lxkeymap

There is a known bug in 12.04 LTS which does not allow to use several keyboard layouts in parallel. Just open Lxkeymap and manually switch the keyboard layout. In 14.04 LTS this bug is fixed and also lxkeymap is not needed.

Tags: keyboard languages lxkeymap User concept, add user student

When installing Lubuntu-Installation the first user created is labdoo (who is also administrator and should be reserved for the teachers, as this user may destroy the system by mistake). If you install via cloning or if you use the installation scripts the additional user student will be created automatically.

The user student kas less rights, e.g. is not able to install or delete software and is not able to destroy the system.

Here is the manuel way, how to create a user student:

45 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Start here → System Tools → User + Groups → unlock → +add user → system password (labdoo) → student as name, e.g. withpassword labdoo → Account Type = Standard (as suggested) → Create → click on password (account disabled) → input of password labdoo and acknowledge → Change → optional: cahnge language of user student.

Open a terminal and type (by executing this zhe user student will become member of the group labdoo): sudo usermod -aG labdoo student (Enter)

Please note: Each new user takes disc space. So please do not create more users.

As a standard user you are not able to destroy a system by mistake (or at least it is very hard). The user labdoo (administrator) should only be used by teachers.

Each user has his own folder and files in the directory /home/....(name of the user). But the folder home/labdoo/Public is a public folder. All users should have access here. To go there open the file explorer → filesystem → home → labdoo → folder /Public (you can add a bookmark to navigate here more easily).

If you add content of your own in /Public there is a script http://ftp.labdoo.org/download/install-disk/installskripts/set-rights-fo... to ensure all rights are set correctly.

In addition there is the user guest. guest needs no password to log-in. But guest is not able to change or store anything. When logging out all his input will be deleted automatically.

Open a terminal and type

sudo apt-get install skype (Enter, tayp password, Enter, answer next question using y)

Only to make sure, if you get the message "Skype not found": Did you add the Canonical Partner Programs as recommended above? Another reason might be you missed to update the software list. so open a terminal and execute sudo apt-get update (Enter).

To get a Skype start icon on the desktop:

Click on the Lubuntu-Start Logo in the left lower corner → click on "Internet" → the list of internet programs will be shown → right mouse click on Skype → Left mouse click on "Add to desktop" → a double click on the Skype icon on the desktop will start Skype.

More details → https://help.ubuntu.com/community/Skype monitor settings (advanced)

If the standard monitor settings of Lubuntu do not fulfil your needs try the tool ARandR, e.g. when you connect a 2nd monitor or a beamer. http://wiki.ubuntuusers.de/RandR#Grafische-Werkzeuge https://help.ubuntu.com/community/Lubuntu/MultiDisplay ARandR offers you a nice user interfaces and advanced options e.g. to make both screens work as one large monitor or as two separted.

Since September 2015 ARandR is part of Labdoo Images for Cloning and of installschript-software.sh.

You can install ARandA as follows:

either open a terminal, sudo apt-get install ARandR (Enter, password, enter)

or

via the Lubuntu Software Centre virus scanner ClamAV

You should not need a virus scanner using Lubuntu. Linux usually needs no virus scanner due to the Linux security concept. There are very few viruses for Linux desktop in the web. Nevertheless some companies offer virus scanner for Linux, e.g. for file server being used also by Windows clients.

Also some edoovillages asked to have a tool to scan USB disc drives of pupils to remove viruses from USB drives of the students. So please install ClamAV for your projects (ClamAV will be installed if you use the installationskript or images for cloning).

So we recommend the license free, open source virus scanner ClamAV https://help.ubuntu.com/community/ClamAV

Open a terminal and execute: sudo apt-get install clamav clamav-freshclam clamav-docs clamav-daemon clamtk (Enter)

And you should install the Firefox Plugin Fireclam, so downloads will be automaticaly checked on viruses using ClamAV. Work in Progress [This is unpublished]

Tags: labdooer Drupal problems

In some combinations (operating system, desktop, browser) the Labdoo.org web-site shows some "strange" behaviour. This wiki chapter is to collect these special problems. As Labdoo.org is only using Drupal as a underlay tool it is beyond our control to solve the problems. Maybe the Drupal team will update and correct the tool (at least we hope...).

If you do not have the problems described below you are lucky :)

Link list of the images for cloning (FTP Server)

Actually there are these Labdoo images available on our FTP-Server http://ftp.labdoo.org/download/images/:

Lubuntu 14.04 LTS

PAE32_14_04_LTS (Lubuntu 14.04 LTS for nonPAE and PAE 32 Bit CPU) PAE64_14_04_LTS (lubuntu 14.04 LTS for 64 Bit CPU)

Special images

PAE32_without_wikidoo (Image without Wikipedia for schools (wikidoo); if hard-disc smaller than 20 GB) PAE64_RACHEL (Image with pre-installed RACHEL; for hard-disc = 80 GB and up)

Double Click on the link of the needed image or right mouse click and "save as".

External disc or USB drive: Please make sure that your disc-drive, where you want to download the image to, is able to handle files larger 4 GB, e.g. NTFS. FAT32 can handle files up to max. 4 GB, then the download will stop. Other disc formats like iOS, Linux may work, but not in combination with all laptops and operating systems. So we recommend NTFS as standard format.

Duration of download: The size of an Labdoo image is +/- 11 GB. If you use e.g. DSL 3000 it may last ca. 10 hours, DSL 6000 ca. 5 hours. But the download time may vary due to your provider, your internet connection, number of parallel downloads, bottle necks between the FTP server (Barcelona) and your place etc.

Please turn off power management circuits or sleep mode during the downloads, because otherwise the download could be interrupted.

14.04 tells you the release date of the Lubuntu release, e.g. 14.04 = April 2014. LTS (Long Term Support) releases will be supported and updated for 5 years, counted from this release date. The next LTS release will be released in April 2016 (16.04 LTS). Knoppix Adriane (technique)

The following modifications

will improve the access from Knoppix Adriane to Labdoo laptops, will improve usage for blind or visually impaired users, just to be used if you eant create a bootable USB stick via Knoppix Adriane and are only recommended to experienced users.

However, these steps are not necessary if

you have performed the installation via Image Cloning [Sanitation Guide: Advanced Method] or within Germany and Switzerland you can obtain 16 GB USB sticks (with pre-installed learning wikipedia) by sending a mail to Labdoo- [email protected]. The Labdoo clubs in Swiss and German will be happyto provide them to you

Suggested changes for Knoppix Adriane (USB Sticks) and Lubuntu

Compiz Settings (only Knoppix Adriane (LXDE), not required for Lubuntu)

Menu → Preferences → CompizConfig Settings Manager →

General → General Options → Desktop size → Horizontal virtual size = 1 Desktop, remove all hooks (Desktop Cube, Expo,Viewport Switcher, Rotate Cube) Effects, remove all hooks, except the one for Windows decoration

Remove Aumix from the starter panel (only for Knoppix Adriane)

Right mouse click on the starter panel → "Application Launch Bar" Settings → click on aumix → - Remove - Close

Pre-Set Adriane as Boot setting within grub (only for Knoppix Adriane)

Open 3 files in an editor e.g. sudo nano /home/knoppix/Desktop/KNOPPIX/boot/syslinux/ and change in the line "DEFAULT" auto into adriane, then store the file:

syslinux.cfg syslnx32.cfg syslnx64.cfg

Optional: You can change the standard screen resolution of Adriane (640x480). But you must choose a resolution supported by the computer used. And visually impaired users might need a low resolution to get large letters. And when you start Adriane if you change the graphical desktop to LXDE it will inherit the resolution of Adriane. You are able to change the screen resolution within LXDE.

Desktop, File manager PCMANFM settings (only Knoppix Adriane)

Open file manager PCmanfm → edit → Preferences → General →

Check to activate "Move deleted files to trash can" de-activate (uncheck) "open files with single click" Volume Management → add check at "Mount mountable volumes" and "Mount removable volumes" Layout → Show in Places → add hook at "Trash can" and "Devices"

Script to toggle screen reader Orca on/off (toggle_orca.sh)

The script toggle_orca.sh solves to toggle the screen reader Orca on / off by using the key combination Alt + Windows/Super + o. The script can be downloaded from here http://ftp.labdoo.org/download/install-disk/installskripts/orca_pico2wav...

Script toggle_orca.sh (for Knoppix Adriane)

Store script in the folder as /home/knoppix/.toggle_orca.sh (the leading "." in the file name will make the file hidden, invisible; to show hidden files activate in PCmanfm "show hidden files", make file executable (→ Properties → Permissions → make file executable) Open Compiz settings manager → General → Commands → if line empty add e.g. in Command Line 2: /bin/sh /home/knoppix/.toggle_orca.sh click on tab "Key Bindings" → click in an empty line on button "disabled" → to switch it to "enabled" → Left mouse click on "grab key ..." type the needed key combination ( here Alt + Windows/Super + o ) → confirm and close "OK".

If everything was done correctly you are now able to switch screen reader Orca on / off by pressing the keys Alt + Windows/Super + o at the same time.

Script toggle_orca.sh to start the window manager Openbox (only Lubuntu)

Same proccedure described before, but store script in folder /usr/share/labdoo (start in a terminal sudo PCMANFM (Enter), as you need super-user rights to create this new folder and store the script) make the script executable → Properties → Permissions. End and close file manager PCMANFM as super-user and start it again as labdoo user (click on icon PCmanfm). open on FTP-Server the file http://ftp.labdoo.org/download/install-disk/installskripts/orca_pico2wav... and copy / paste the content (Ctrl + C) activate in file manager PCMANFM → menu View → Show hidden (Ctrl + H) and open in folder /home/labdoo/.config/openbox the file lubuntu-rc.xml in an editor (right mouse click, open in an editor e.g. Leafpad) Search in the editor for the text , next insert the copied text from clipboard between the lines and . The code from file keybinding_toggle_orca.txt will be inserted. Store and close file. execute in terminal openbox --reconfigure repeat these steps also for the user student, but as student is not allowed to run code in a terminal you have to go to Start → Run → type here openbox --reconfigure and press Enter.

If everything was done correctly you are now able to switch screen reader Orca now on / off by keep the keys Alt + Windows/Super + o at the same time.

Set-up tool pico2wave (for Knoppix Adriane and Lubuntu)

To install it run in a terminal, when computer is connected to web:

1. in terminal: sudo apt-get update (Enter) 2. in terminal: up to 16.04 LTS: sudo apt-get install libttspico-utils sox xsel libav-tools (Enter) 3. in terminal: from 18.04 LTS: sudo apt-get install libttspico-utils sox xsel libavcodec-extra (Enter)

Beside the installation of pico2wave 3 more files have to be installed and adapted (for Lubuntu: in /usr/share/labdoo, in Knoppix in /home/knoppix/.). Please follow those steps described above for Orca:

First step is to download the needed files from our FTP-Server and store it locally: Control script to toggle pico2wave on / off (pre-set to English): toggle_pico2wave.sh next to get a German pronunciation (DE): pico2wave_xsay_de.sh or for English pronunciation (EN): pico2wave_xsay_en.sh ; more languages on request Script to end pico2wave: pico2wave_kill-xsay.sh

Download and store these files in the corresponding folders and make files executable for everyone.

Volume settings (Knoppix Adriane and Lubuntu)

Open in a terminal → alsamixer → (m) = Mute off, move from setting to setting by ← or →, adjust volume setting using the keys ↑ or ↓.

Mount the disc drive of a Labdoo laptop (/sda1) when booting (only Knoppix Adriane)

Helpful, if you run Knoppix Adriane on a USB Stick in combination with a Labdoo laptop, to get easier access to the educational content. Open an editor as super-user; run in a terminal sudo leafpad (Enter), navigate to the folder:

open file /etc/fstab and change lines: # Automount sda1 as sda1 /dev/sda1 /media/sda1 ext4 defaults 0 2 Store file. Add to the end of /etc/adriane/adriane.conf: # Mount sda1 sudo mkdir /media/sda1 sudo mount -a Store file.

Hint: In Adriane you can open a terminal → menu entry → Shell.

Adapt LXDE panel to look alike as on a Labdoo computer (only Knoppix Adriane)

Add needed applets for Keyboard activation/deactivation etc. to the panel.

Add bookmarks to elinks Browser (for Knoppix Adriane and Lubuntu)

Start eLinks → navigate to the start file, in most cases index.html), mark it with the cursor and press (Enter) to open it → right mouse click opens a menu, click here → Bookmark document (a) → ready.

To open a bookmark → press two times ESC → above a menu will show up → move the cursor and mark tools , press Enter → mark bookmarks

Tags: knoppix adriane installation usb disc blind visually impaired Generate a Knoppix Adriane USB disc drive

There are several ways to get an USB-disc drive (stick) with Knoppix Adriane software and educational content for blind users:

1. you can ask Labdoo to send out a ready installed USB-disc drive (stick) by sending a m to Labdoo-DACHqLabdoo.org (only for Austria, Germany and Switzerland). Tell us how many USB-Discs you need and your postal address. Please understand that we have to cover the costs by donations. 2. Or you produce an USB-disc drive yourself (only recommended for advanced users!) It will NOT WORK to copy an USB-disc to another USB-disc using a file manager. Some important data like boot information (MBR) will not be copied and will not be able to boot this stick. Labdoo recommends minimum 16 GB USB 2.0 disc drives to store Knoppix Adriane, local Wikipedia for Schools and ca. 6GB free space for user data.

You can get another USB disc drive

by copying a pre-installed USB-disc drive to another drive using Linux and the dd command (for details see below) or download an image and restore it using dd command..

Method 1: Copy one pre-installed USB-disc drive to another (only for experienced users)

You already have got a pre-installed USB-disc drive Knoppix Adriane by Labdoo? Then buy an USB-disc drive (min. 16 GB). As only very few of the computers abroad have USB 3.0 slots we recommend to buy fast USB 2.0 disc drives. On older hardware USB 3.0 discs might not be recognized.

You can do de copy using a Labdoo- or Linux laptop: Start the Labdoo-/Linux computer and log-in as user labdoo. Important: First plug-in the pre-installed origin USB-disc (which you want to copy, will usually get the name /sdb), next plug-in the USB drive you want to copy to (will get drive /sdc etc.) You are also able to copy several sticks at the same time (will become drive /sdd, /sde etc).

Open a terminal and run lsblk -f (Enter). This will give you a list of all available drives. The drive /sda (mit den Partionen /sda1, /sda2 usw.) is the internal drive of the laptop. Never touch that! Leave it as it is!

Next step is to run in a terminal: sudo dd if=/dev/sdb of=/dev/sdc status=progress Enter; this will copy all data from the origin USB drive (/sdb) to the target USB drive (/sdc etc.). This will take a while...

Attention: the command dd is helpful, but also dangerous! Check always, if origin and target drive are correct. Otherweise you might delete your own computer's data by mistake. We recommend not to use your own computer, but a Labdoo computer since dd is available on each Linux computer.

Method 2: Restore the image Knoppix_Adriane_dd_xx.gz using dd to an USB disc drive (only recommended for experienced users)

Download from the Labdoo FTP-Server the images (we created them using dd): http://ftp.labdoo.org/download/install-disk/ (the images are named Knoppix_Adriane_dd_xx.gz, xx being space-holder for the language, EN = Englisch, FR = Französisch, DE = Deutsch, ES = Spanisch)

Store the downloaded, zipped file in your home directory (/home/labdoo). You don't need to unzip it first. Next step is to connect the target USB disc drive to the computer, open a terminal and execute :

1. lsblk -f (Enter), to check if all drives are connected (in most cases the internal disc of the computer is /sda (do not delete that one!) and the connected USB disc drive becomes /sdb, /sdc etc. 2. sudo gunzip -c Knoppix_Adriane_dd_xx.gz | sudo dd of=/dev/sdb status=progress (Enter, xx = space-holder for the language, replace accordingly). This will unzip and copy all data of the image to the USB drive. Change drive name accordingly if needed, e.g. /sdb in /sdc etc. if copying several USB drives in parallel

After copying all data to a new USB drive you can unmount (remove secure) and shut down the computer. To use this new USB drive with a computer we recommend to change the boot sequence in BIOS settings. The USB-(stick) should be placed (get a higher boot priority) before the internal disc drive. Otherwise you can select manually the boot media each time you boot (often press F12). But for blind users this might be difficult.

Internal: Create an image using Shell and dd (only recommended for experienced users!)

To get an image from an ready installed USB disc drive with Knoppix Adriane use dd as well. In most cases the USB disc, to copy from, has the address / drive name /sdb (might change, so please check).

Create image by terminal (shell) Open a terminal and execute sudo dd if=/dev/sdb status=progress | gzip --best >Knoppix_Adriane_dd_xx.gz (Enter, replace xx by the language code you need). This will copy a zipped image file Knoppix_Adriane_dd_xx.gz an (ca. 12 GB) to your home directory /home/labdoo.

Sanitation Guide: Advanced Method

There are two different advanced methods. The 'Advanced Method (Without Network)' will allow you to clone Labdoo laptops from your USB or DVD drive and without the need to use a network. The 'Advanced Method (With Network)' will allow you to clone Labdoo laptops from a server and over the network.

Please notice that these methods are mutually exclusive. Choose one method or the other, depending on your preferences and resources.

If you have any questions, remember that you can write them to the Labdoo quality assurance team wall and someone will provide the answers.

Choosing the Right Labdoo Images for your Computer

Both advanced methods use Labdoo images to install the complete operating system and educational packages. Use the following table to choose the correct image depending on your computer.

Figure. Choose your Labdoo image by following these steps.

Tags: guide sanitize advanced software grassroots Advanced Method (Without Network)

Introduction

This wiki page will guide you through the process of sanitizing a laptop and installing the education software according to the advanced method (without network). The advanced method is based on the process of cloning the Labdoo/Lubuntu image, which includes all the necessary software. This process is a bit more complex than the sanitation process based on the simple method, but its advantage resides in that it will allow you to sanitize laptops and install a very large and complete education package in a more efficient and speedier way.

Sanitation Steps

Follow the next steps to sanitize a Labdoo laptop according to the advanced method. If you have any questions or doubts through the process, please post your queries in the Labdoo Quality Assurance Team and another Labdooer will provide an answer.

Embedded in the descriptions of each of the following steps you will also encounter some videos. We recommend you to watch them as they provide valuable graphical insights about the installation process.

Video. Advanced method part 1.

PartedMagic / Clonezilla: how to clone a Labdoo laptop. Part 1 (…

1. Download Parted Magic tool.

Start first by downloading the license-free tool Parted Magic. Choose to download the Parted Magic image from one of the following two links:

51 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Parted Magic / Clonezilla 2012/10: We recommend you to use this version which should work for older and modern laptops. Parted Magic / Clonezilla 2013/08: In some cases the 2012/10 version may fail depending on the laptop. For these cases, try the 2013/08 version.

Download and burn the Parted Magic ISO image into a bootable CD or a USB stick.

2. Start Parted Magic.

Insert your Parted Magic CD or USB stick into the laptop you want to sanitize and boot it. (Make sure that the bios of your laptop is set to boot first from the CD drive or from the USB stick. For information on how to configure the booting order using the bios please refer to this page.)

Once Parted Magic starts, select the default option 'Default settings (Runs from RAM)'. This option should work for most of computers, but if you find any issues, you can manually set a different configuration by using the various options found in the Parted Magic menu. In this case, see also the above video for an explanation of some of the options.

Once parted magic has completed booting, you will be presented with a graphical desktop with various icons. It's important to start by deleting all the data from the laptop hard disk to ensure all previous private information is erased. You can do this by clicking on the icon 'Disk eraser' and follow the instructions. The deletion can take some time, so go grab a cup of coffee in the meantime if needed.

3. Download the Labdoo/Lubuntu ISO image.

Prior to selecting a proper Lubuntu/Edubuntu image for your laptop, you need to know what type of laptop you have. To do so, once Parted Magic is booted, click on the black screen icon found in the task bar at the bottom of your screen. This will open a terminal window. In this terminal, type the following command:

grep -q 'lm' /proc/cpuinfo && echo "My CPU is a 64 bits one" || echo "My CPU is a 32 bits one"

The output will tell you whether you have a 32 or a 64 bit computer. Based on this information, you can now download the most suitable Labdoo image from the following link: http://ftp.labdoo.org/download/images/

Notice that there are different images, so you will need to make sure you download the right one based on the characteristics of your laptop and the type of education software you want to install. The following README file (located also in the above link folder) describes each image and will help you decide the right image for your laptop: http://ftp.labdoo.org/download/images/README-EN.txt

You can also refer to the following diagram to decide which image is best for your computer:

Figure. Choose your Labdoo image by following these steps.

Store the downloaded zipped image file on an external USB disk-drive/memory stick or in another computer connected to your local network. If you handle several images create a folder for each image and copy each image into its own folder. If you are using a local device such as a USB disk or memory stick, please store these image folders under the first top level folder to ensure that Clonezilla (described in the next step) will be able to find them.

Now go to that folder and unzip the downloaded file using the following command:

tar zxf FILENAME.tar.gz

(substitute FILENAME by the name of the file). This will uncompress the downloaded file.

Each Labdoo image comes with a checksum file containing an MD5SUM value. Using this MD5SUM value you can check if the download was completed with no errors. How to handle and compare MD5SUM depends on the operating system of your computer. To compare the MD5SUM using a Linux machine, open a terminal and go into the folder where both the unzipped file and the MD5SUM file are located and execute the following command:

md5sum -c MD5SUM

To learn more about MD5SUM you can check: https://en.wikipedia.org/wiki/MD5

4. Install the Labdoo/Lubuntu image.

Labdoo images are complete copies that include all the operating system and education software. So by cloning them into your laptop, you will have a newly sanitized computer ready to deliver education to children. Follow the next steps to carry out the cloning process.

While running Parted Magic, double click the icon 'Clonezilla' to start the image cloning process. Select the option 'Image' (instead of device). Next, select the 'Storage Media' on which the Labdoo/Lubuntu image you downloaded in the previous step is stored. Read the instructions on the screen as they will guide you too. Next, select 'Expert Mode'. We need to use expert mode because the Labdoo/Lubuntu image 'remembers' the size of the original disk upon which it was created. If the target disk in the new cloned laptop is smaller, you will get an error in beginners mode ('target disk too small'). In Expert Mode you can enable the option '-icds' to avoid this check (see below). Select 'Restore Disk' to restore the image. Select the Labdoo/Lubuntu image that you previously downloaded.

52 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Select the target disk. Mark in expert mode the option list '-icds' by using the space button ('do not check if the size of the origin disk is larger than the target disk'). Answer the following questions with "Y" (Yes). At this point, the cloning process will start and it will last from 15 to 30 minutes. Once finished, the complete Lubuntu operating system plus all the education software and Labdoo settings are installed and ready to use! This is the big advantage of using this cloning process, if you were to instead download all the education packages from the Internet it would take you a good amount of hours.

Note: If you are cloning a 14.04 image (or higher) using 'Clonezilla 2012/10' you may get at the end two red error messages saying that certain GRUB files and settings are missing. You can ignore this message, everything is ok.

5. Steps to complete the configuration of the laptop after the cloning process.

Video. Advanced method part 2.

PartedMagic / Clonezilla: how to clone a Labdoo laptop. Part 1 (…

Once you have completed the previous cloning process, start the Partition Editor by clicking on the Gparted Icon found on the desktop. This tool will help you adapt the size of your computer through the following steps:

Click on the Linux swap space, click on the option "Resize / Move" and drag it using the mouse to the end of the disk (please make sure that the mouse pointer shows arrows to the left AND to the right side, as otherwise you will be enlarging the swap space instead). The swap size also needs to be adapted to the size of the memory (RAM) of your laptop. Both should match. For instance, if your laptop's RAM is 1GB, configure your swap partition to be also 1GB. Use the mouse or fill in the data you need in the shown table. Then press OK. Next step is to enlarge the data / software partition, usually named partition 'sda1'. Click at the end of this partition and drag it all the way to the right. A small gap (1 MB) will be left which cannot be used, that is ok. Click on the green hook 'Apply' and confirm it. The computer will then be busy for a while adjusting the partition sizes. Once the computer finishes the previous process, reboot it by clicking on the lower left corner of the screen of the Parted Magic desktop. You laptop is now ready to help unleash education somewhere in the planet!

Tags: advanced sanitize software image edubuntu ubuntu lubuntu Advanced Method (Without Network): Autodeploy (In BETA)

BETA NOTE: this page describes a new method to install Labdoo images which is currently under trial and development. This method will likely replace our current "Advanced Method (Without Network)" installation method although currently it's still in beta phase. Feel free to try it out and provide feedback. If in doubt, use our default "Advanced Method (Without Network)" or "Advanced Method (With Network)" methods described in the previous sections.

Introduction and Approach This method consists in using the script "autodeploy.sh" which automates most of the steps in the installation process. By using this script, you will avoid having to manually perform steps such as deleting data using Parted Magic, selecting the matching image, or adapting the partitions among others, because the script autodeploy.sh performs this automatically.

The autodeploy script will perform these tasks automatically:

Deleting data from the hard disk using random generated data. Selecting the best matching image for cloning your computer, depending on the CPU type (32 or 64 Bit) and the size of the hard drive. (See diagram below.) Installation of the matching image from an external drive. (Either from an external USB drive or from a server.) Calculation of the best size for the swapping partition and adapting the swapping space. Writing of the the installation protocol into a protocol file.

After using the script, the computer is ready to be used except for the final steps to adapt it to the needs of the destination school/edoovillage. You will be able to directly go to the Section Post-Installation Configuration to perform these final adjustment steps.

Figure. The auto deploy script automatically chooses the best Labdoo image based on the specifications of each computer.

53 von 97 18.10.20, 09:31 Information for Labdooers (Volunteers) https://www.labdoo.org/de/book/export/html/35

Running the Autodeploy Script

In this section we detail the steps that you need to follow to install a Labdoo image using the Autodeploy script:

Save the executable script autodeploy in a storage of your choice, typically in an USB disk or a server. Boot Parted Magic. [Note: the script autodeploy.sh runs on Parted Magic (10.2012 and 08.2013)] Once parted magic is booted, copy the autodeploy script to your computer. Open the File Manager (double click on the blue icon in the upper left corner of the desktop). Clicking on the left column to the drive containing the script (e.g. on a USB drive) will open a 2nd tab. Right mouse click on the script you want to copy (Copy). Click on the 1st tab (root), right mouse click to paste the script to the "/root" directory. Open a terminal, click on the terminal icon in the task bar. Type in terminal /root/autodeploy.sh [Enter] Follow the instructions from the script

Adapting the Autodeploy Script (only recommended for advanced users)

In some occasions you may need to modify the autodeploy script to adjust its behavior to your specific needs or goals. The next descriptions explain some of the options you can modify in the script.

[Note: line numbers may change depending on the version of the script you are using, but the same concept applies.]

[Hint: By adding or removing # lines in the script can be activated or deactivated.]

Lines 5-8: Names of the images for cloning (please do not change these parameters, as the names are preset by the Labdoo team.) Lines 10-11: Shut down the computer automatically after the installation is finished (0=no/Default; 1= yes). Lines 13-14: Example to connect to a local server (LAN); paths and passwords have to be set as needed in your local network. If in doubt contact your local administrator.

# We thank the team of Labdoo Hub Düsseldorf (Germany) for developing this time-saving script!
