GNOME OS and Proposed GNOME Patches

Published on Tux Machines (http://www.tuxmachines.org) Home > content > GNOME OS and Proposed GNOME Patches GNOME OS and Proposed GNOME Patches By Roy Schestowitz Created 28/07/2020 - 2:29pm Submitted by Roy Schestowitz on Tuesday 28th of July 2020 02:29:07 PM Filed under GNOME [1] GNOME OS Images Available For Testing [2] GNOME OS as the Linux build with bleeding edge GNOME software for testing continues taking shape and a call for testing has been issued. For GNOME module maintainers and other interested individuals, a call for testing of GNOME OS was issued today for the latest operating system images. While GNOME OS is improving with its hardware support, this call for testing is focused on using GNOME Boxes or other virtualization software for firing up this bleeding-edge version of GNOME. GNOME OS call for testing (+BuildStream workshop) [3] Hi all, As most of you have probably heard by now, our nightly VM images are ready for wider testing. I'd like to ask at least maintainers of GNOME core modules to test it. Core modules are defined in https://gitlab.gnome.org/GNOME/gnome-build-meta/-/tree/master/elements/core I'd also like to request maintainers of core modules to review the way their modules (and their dependencies) are built, and file bugs if the apps doesn't work correctly or would prefer it to be built with a different set of options. The image can be downloaded from https://gitlab.gnome.org/GNOME/gnome-build-meta/-/jobs/artifacts/master/raw/image/disk.img.xz?job=vm-image-x86_64 To run it with you distro version of gnome-boxes (or anything that uses libvirt), first decompress it, then run: virt-install --name GNOMEOS --boot uefi --video virtio --memory 2048 --import --disk disk.img To run it in nightly flatpak of gnome-boxes, decompress and convert to qcow2 using: qemu-img convert disk.img disk.qcow2 then from gnome boxes, add a new virtual machine, select "GNOME Nightly x86_64" and select the qcow2 image. The image uses the "user" variant by default, and can be updated using GNOME Software, or using the command line: sudo ostree admin upgrade If you'd like to try the developer image, use sudo ostree admin switch GnomeOS:gnome-os/master/x86_64-devel you can switch back to the user image using sudo ostree admin switch GnomeOS:gnome-os/master/x86_64-user Lastly, I'd like to announce that we're going to do an informal workshop on using BuildStream to develop GNOME components starting at 16:00 UTC on the GUADEC platform. That's about 3 and half hours from now. Regards, Abderrahim Proposed GNOME Patches Would Switch To Triple Buffering When The GPU Is Running Behind[4] The latest GNOME performance work being explored is effectively how to make the Intel graphics clock speed ramp up quicker when necessary. Canonical developer Daniel van Vugt is working on a set of patches for enabling triple buffering with Mutter when the GPU starts falling behind and that additional rendering work in turn should ramp up Intel GPUs to their optimal frequency in order to smooth out the performance. Daniel has been working on various GNOME desktop optimizations focused primarily on Intel graphics and at 4K. He had been seeing the modern Intel "Iris" Gallium3D driver at times delivering lower performance than the classic "i965" driver. On investigation, he found that it wasn't due to the OpenGL driver per se but the iGPU was running in a lower clock/performance state.

An User & Developer Perspective on Immutable Oses
An User & Developer Perspective on Dario Faggioli Virtualization SW. Eng. @ SUSE Immutable OSes [email protected] dariof @DarioFaggioli https://dariofaggioli.wordpress.com/ https://about.me/dario.faggioli About Me What I do ● Virtualization Specialist Sw. Eng. @ SUSE since 2018, working on Xen, KVM, QEMU, mostly about performance related stuff ● Daily activities ⇒ how and what for I use my workstation ○ Read and send emails (Evolution, git-send-email, stg mail, ...) ○ Write, build & test code (Xen, KVM, Libvirt, QEMU) ○ Work with the Open Build Service (OBS) ○ Browse Web ○ Test OSes in VMs ○ Meetings / Video calls / Online conferences ○ Chat, work and personal ○ Some 3D Printing ○ Occasionally play games ○ Occasional video-editing ○ Maybe scan / print some document 2 ● Can all of the above be done with an immutable OS ? Immutable OS: What ? Either: ● An OS that you cannot modify Or, at least: ● An OS that you will have an hard time modifying What do you mean “modify” ? ● E.g., installing packages ● ⇒ An OS on which you cannot install packages ● ⇒ An OS on which you will have an hard time installing packages 3 Immutable OS: What ? Seriously? 4 Immutable OS: Why ? Because it will stay clean and hard to break ● Does this sound familiar? ○ Let’s install foo, and it’s dependency, libfoobar_1 ○ Let’s install bar (depends from libfoobar_1, we have it already) ○ Actually, let’s add an external repo. It has libfoobar_2 that makes foo work better! ○ Oh no... libfoobar_2 would break bar!! ● Yeah. It happens. Even in the best families distros

GNOME Annual Report Fiscal Year 2013
GNOME Annual Report Fiscal Year 2013 GNOME Annual Report 2013 Letter from the GNOME Foundation 3 Hackfests 4 Conferences 6 Internship programs 8 Finances 10 Accessibility 11 Privacy campaign 12 Bugzilla statistics 13 GNOME releases 14 Advisory Board 17 Friends of GNOME 18 Credits 20 1 Letter from the GNOME Foundation It is bittersweet to be introducing the 2013 GNOME annual report. This financial year was my last year as GNOME's Executive Director, as I left the position in March of 2014. However, I'm thrilled to have recently been elected to GNOME's Board of Directors and am happy to continue to contribute to GNOME's future. GNOME is such an important, vibrant project, and I feel lucky to be able to play a part in it. As you will see when you read this annual report, there have been a lot of great things that have happened for the GNOME Foundation during this period. Two new companies joined our advisory board, the Linux Foundation and Private Internet Access. The work funded by our accessibility campaign was completed and we ran a successful campaign for privacy. During this period, there was a fantastic Board of Directors, a dedicated Engagement team (who worked so hard to put this report together), and the conference teams (GNOME.Asia, GUADEC and the Montreal Summit) knocked it out of the park. Most importantly, we’ve had an influx of contributors, more so than I’ve seen in some time. I hope that I have helped us to get in touch with our values during my time as Executive Director and I think that GNOME is more aware of its guiding mission than ever before.

Hello Everyone. I Introduce You Voyager GE 19.04 That Continues the Adventure with the Desktop Gnome Shell Version 3.32 by Introducing New Features
Hello everyone. I introduce you Voyager GE 19.04 that continues the adventure with the desktop Gnome Shell version 3.32 by introducing new features. With the promise finally realized to have a light Gnome system, fast, fluid and powerful. This version is based on the Linux 5.0 kernel and distribution Ubuntu Disco Dingo . 19.04 is an intermediate version upgrade nine months preparing the future version 20.04 LTS - Long-term Support - 5 years that happens every two years, when Voyager will be available in 2 versions, GNOME Shell and Xfce. Also you can choose according to your wishes and capacity machines. The general idea of Voyager is to introduce in Gnome Gnome Shell preinstalled extensions and scripts grouped in a box that optimize the system with a choice of necessary software. A video presentation and pictures are available. Soon for this new human and digital adventure. Voyager wants multi-profile and multi-task in an environment aesthetic and immersive as possible and that, from the origins of traveling, so that time spent on your machine is the most pleasant. In summary, the general idea is that for each profile, we have options available types that can activate or not. Voyager GE 19.04 based on Ubuntu 19.04 will cycle nine months of support and updates. For information, these are intermediate versions that prepare Future LTS. You can then seamlessly transition to 19.10 with automatic up-to-date system and so on until the next LTS. Voyager GE is not a distribution with its deposits but a customized variant of Ubuntu as mentioned above, with all its official repositories.
