XWN740: Session / Window Managers Desktop Environments Lab #4 XWN740: Session / Window Managers Desktop Environments Lab #4 PURPOSE: To learn about the gnome default session manager, and how to customize an X Windows graphical environment by using different window managers. This lab will also demonstrate how to launch an X windows display using only a window manager and a client application. INSTRUCTIONS: Perform each of the following steps in sequence. Answer all questions, and submit answers to your instructor (Refer to the section titled SUBMISSION INSTRUCTIONS at the bottom of this lab). Keys are denoted by < and > signs. PERFORM THE FOLLOWING STEPS 1. In the Seneca computer lab, login graphically in Fedora 8 Test account server. Login as joker using the password seneca99 (Note: This lab will require you to install programs using the yum utility. It is recommended to either run yum update command in advance of performing this lab in T2107 or perform this lab on another computer system with Fedora Core 9 installed) 2. Open a shell prompt (eg. xterm). A session manager (SM) is responsible for saving and restoring the session state; this allows the user to log out and later log in, and to findÐmore or lessÐthe same programs running. How is this done? The SESSION_MANAGER environment variable is used to store the communication path used between the session manager and the clients. In this way, the session manager can store the ªsaved stateº of each application (client) window. 3.At the shell prompt, issue the following command: echo $SESSION_MANAGER Question #1: Write down the contents of the DISPLAY_MANAGER environment variable. XWN740: Session / Window Managers Desktop Environments Lab #4 This file pathname represents a socket which is a ªcommunicationº channel that allows the SESSION MANAGER to communicate with the client applications in order to store the saved state information, or to restore the saved state. Unfortunately, information regarding the saved state such as the Session ID number is basically used for internal purposes, so it is hard to issue commands to view this information from a file. On the other hand, there are utilities to allow the user to view certain characteristics of the programs that the Session Manager launches. In gnome, the program gnome-session-properties provides Session Manager properties. It is also available from the SYSTEM menu, under PREFERENCES, and then SESSSION (although the location may be different based on other Linux Distributions). 4. At the shell prompt, issue the following command: gnome-session-properties 5. In the Session Preferences dialog box, click on the Current Session tab. Question #2: Write down the programs that are currently running (running programs show a ªgearº icon under the ªstateº heading). Question #3: What version of the Window Manager(WM) is running? 6. Click on the Session Options tab. Note this is where you can have the Session Manager remember the state of the saved X Window client applications. Note: It is usually left up to the client application itself if it wants to use this data available from the Session Manager to restore itself in a new X Windows session.... 7. Close the Session Preferences dialog box. A window manager (WM) is responsible for managing window placement and provide window decorations. The window manager communicates with the session manager in order to render application windows that remained opened when the user exited the X Windows session. There are numerous versions of window managers each having their own advantages and features. We will now explore running your X windows sessions in several different window managers, and record their appearance. XWN740: Session / Window Managers Desktop Environments Lab #4 8. Login to the terminal as superuser, and remain in superuser unless otherwise notified. 9. Make certain that you are connected to the Internet. Load the updated repositories by issuing the following command: yum update # Note: This may take some time... 10.Install each of the following Window Managers by using the yum command (For example: yum install blackbox) blackbox enlightenment icewm openbox 11.Install the web-browser called Galeon by issuing the following command: yum install galeon 12.Move to your first text-based virtual terminal (vt1), and login as joker. Use the X :1 & command to launch an X Windows session in Display #1. 13.Return to virtual terminal #1 and issue the following command: xterm -display :1 & 14.Return to your graphical display #1. You should see a plain xterm application running. 15.Issue the following command in the xterm application window: /usr/bin/metacity Question #4: What did you notice about the characteristics of the xterm window? 16. Press <CTRL><c> in the xterm window to terminate the foreground process (i.e. the process this is currently running) XWN740: Session / Window Managers Desktop Environments Lab #4 Question #5: Repeat steps 15 and 16 for each of the 4 Window Managers that you downloaded. If necessary issue the ªwhichº command to determine the pathname of that window manager (eg. Which blackbox). Briefly compare each WM characteristic. Question #6: Based on your initial observations, is there a window manager that you like better than the default metacity (motif window manager) in lab T2107©s Gnome session? Sometimes a full-blown desktop environment can be overkill, particularly on a machine with limited memory or CPU resources, or when the user will be limited to a small range of tasks. We will now configure a shell script that will run just a windows manager and a web-browser application in an X windows session using several window managers. The ~/.xinitrc file can be configured by the user to customize their X windows session when using the startx command. 17.Terminate the graphical X windows session for Display :1, and return to the first text based virtual terminal (vt1). 18.Create a file called .xinitrc in your home directory, and add the following lines of text displayed below: #!/bin/sh # Start an X server with specific characteristics # === CONFIGURATION VARIABLES === # Window manager binary name (twm, mwm, etc). WM=twm # === SET ROOT WINDOW BG COLOR TO BLACK === /usr/bin/bsetroot -display :1 -solid black & # Start window manager - server will be terminated # when the window manager exits $WM& sleep 2 # === START CLIENT === XWN740: Session / Window Managers Desktop Environments Lab #4 /usr/bin/galeon https://learn.senecac.on.ca/ -f # End of Bourne Shell script Issue the command startx -- :1 and note what happens to the appearance, and what happens when you close the web-browser. 19.Try editing the ~/.xinitrc file for some of the following window managers below, and start your X windows sessions in DISPLAY :1 to see what happens... icewm blackbox awesome afterstep 20. You have completed this lab. Close your X window session for DISPLAY :1 and proceed to ªSUBMISSION INSTRUCTIONSº... SUBMISSION INSTRUCTIONS Send an e-mail message to your X Windows instructor with Subject line: ªXWN740 ± Lab4º. Your e-mail message must contain the answers to each of the 6 questions. I prefer you write a couple of paragraphs to answer these questions, but also what you learned (or didn©t learn) from this lab. It is also recommended to post feedback from performing this lab on your blog... You have one week from the date and time of this lab to submit the answers to this lab... ASSIGNMENT CONSIDERATIONS Go to the Open Source at Seneca Wiki (URL: http://zenit.senecac.on.ca/wiki/index.php/Main_Page ) A group member has proposed several possible sites to conduct a discussion for this assignment that leaves a better trail for communication purposes. It is up to this class to select one and place XWN740: Session / Window Managers Desktop Environments Lab #4 a link to that discussion group for all members to participate. You will still be using the Arcade wiki, but I would also expect to see XWN740 students participating in the discussion group.....

  • Part II, Window Managers and Desktop Environments
    Part II Window Managers and Desktop Environments The window manager is responsible for managing application windows and application- independent behavior, such as pop-up menus appearing in the background. The window manager manages the placement, borders, and decorations of all windows, and is responsible for the look and feel of your particular X session. Desktop environments typically include an integrated window manager, some sort of control panel, applications, and a consistent look and feel across applications. The chapters in Part II, Window Managers and Desktop Environments, are: Overview This chapter provides a conceptual introduction to window managers and desktop environments and briefly surveys some of the many window managers and desktop environments available for Linux. FVWM FVWM is a traditional window manager for Linux systems. It is now into its second major version, FVWM2. Window Maker Window Maker is an elegant X11 window manager designed to give integration support to GNUstep-based applications. It emulates the look and feel of OpenStep, the NeXTSTEP GUI. Enlightenment Enlightenment, often shortened to just E, may be the most elaborate and bizarre window manager available. Enlightenment’s motto, “time to rethink everything,” provides a good indication of the uniqueness and flashiness behind Enlightenment. Using GNOME GNOME, which stands for GNU Network Object Model Environment, is a freely available desktop environment that can be used with any of several window managers, including Enlightenment and Sawfish. Using KDE KDE, the K Desktop Environment, is another freely available desktop environment. KDE includes an assortment of games and utilities, as well as an integrated suite of office productivity applications..

  • Easy Slackware
    1 Создание легкой системы на базе Slackware I - Введение Slackware пользуется заслуженной популярностью как классический linux дистрибутив, и поговорка "кто знает Red Hat тот знает только Red Hat, кто знает Slackware тот знает linux" несмотря на явный снобизм поклонников "бога Патре­ га" все же имеет под собой основания. Одним из преимуществ Slackware является возможность простого создания на ее основе практически любой системы, в том числе быстрой и легкой десктопной, о чем далее и пойдет речь. Есть дис­ трибутивы, клоны Slackware, созданные именно с этой целью, типа Аbsolute, но все же лучше создавать систему под себя, с максимальным учетом именно своих потребностей, и Slackware пожалуй как никакой другой дистрибутив подходит именно для этой цели. Легкость и быстрота системы определяется выбором WM (DM) , набором программ и оптимизацией программ и системы в целом. Первое исключает KDE, Gnome, даже новые версии XFCЕ, остается разве что LXDE, но набор программ в нем совершенно не устраивает. Оптимизация наиболее часто используемых про­ грамм и нескольких базовых системных пакетов осуществляется их сборкой из сорцов компилятором, оптимизированным именно под Ваш комп, причем каж­ дая программа конфигурируется исходя из Ваших потребностей к ее возможно­ стям. Оптимизация системы в целом осуществляется ее настройкой согласно спе­ цифическим требованиям к десктопу. Такой подход был выбран по банальной причине, возиться с gentoo нет ни­ какого желания, комп все таки создан для того чтобы им пользоваться, а не для компиляции программ, в тоже время у каждого есть минимальный набор из не­ большого количества наиболее часто используемых программ, на которые стоит потратить некоторое, не такое уж большое, время, чтобы довести их до ума. Кро­ ме того, такой подход позволяет иметь самые свежие версии наиболее часто ис­ пользуемых программ.

  • Towards a New Enlightenment? a Transcendent Decade
    Towards a New Enlightenment? A Transcendent Decade Preface This book, Towards a New Enlightenment? A Transcendent Decade, is the eleventh in an annual series that BBVA’s OpenMind project dedicates to disseminating greater knowledge on the key questions of our time. We began this series in 2008, with the first book, Frontiers of Knowledge, that celebrated the launching of the prizes of the same name awarded annually by the BBVA Foundation. Since then, these awards have achieved worldwide renown. In that first book, over twenty major scientists and experts used language accessible to the general public to rigorously review the most relevant recent advances and perspectives in the different scientific and artistic fields recognized by those prizes. Since then, we have published a new book each year, always following the same model: collections of articles by key figures in their respective fields that address different aspects or perspectives on the fundamental questions that affect our lives and determine our futu- re: from globalization to the impact of exponential technologies, and on to include today’s major ethical problems, the evolution of business in the digital era, and the future of Europe. The excellent reaction to the first books in this series led us, in 2011, to create OpenMind (www.bbvaopenmind.com), an online community for debate and the dissemination of knowle- dge. Since then, OpenMind has thrived, and today it addresses a broad spectrum of scientific, technological, social, and humanistic subjects in different formats, including our books, as well as articles, posts, reportage, infographics, videos, and podcasts, with a growing focus on audiovisual materials.
