GNOME Shell Development Updates

GNOME
  • GNOME Shell + Mutter Begin Landing Graphene Integration

    Graphene is a lightweight library that has been in development by GNOME's Emmanuele Bassi. Graphene -- not to be confused with several other software projects sharing similar names -- is intended as a very lightweight library providing graphics types and their relative API while avoiding any windowing system bits and other functionality with this layer just focused on providing speedy vector operations. Graphene has fast paths for SSE2, ARM NEON, GCC Vector extensions, and other optimizations for optimally dealing with graphic data types like matrices, vectors and points.

    [...]

    With part 1, various geometry/point/rectangle/vector Clutter objects are replaced with Graphene code. Ultimately this should provide for better performance around various graphic data type operations while also cleaning up some of GNOME's low-level code in the process. This initial integration is now in place for the initial GNOME 3.35/3.36 series though expect more Graphene improvements to come now that the initial support and dependency are in place.

How GNOME uses Git

Filed under
GNOME

“What’s your GitLab?” is one of the first questions I was asked on my first day working for the GNOME Foundation—the nonprofit that supports GNOME projects, including the desktop environment, GTK, and GStreamer. The person was referring to my username on GNOME’s GitLab instance. In my time with GNOME, I’ve been asked for my GitLab a lot.

We use GitLab for basically everything. In a typical day, I get several issues and reference bug reports, and I occasionally need to modify a file. I don’t do this in the capacity of being a developer or a sysadmin. I’m involved with the Engagement and Inclusion & Diversity (I&D) teams. I write newsletters for Friends of GNOME and interview contributors to the project. I work on sponsorships for GNOME events. I don’t write code, and I use GitLab every day.

10 Ways to Customize Your Linux Desktop With GNOME Tweaks Tool

Filed under
Linux
GNOME

There are several ways you can tweak Ubuntu to customize its looks and behavior. The easiest way I find is by using the GNOME Tweak tool. It is also known as GNOME Tweaks or simply Tweaks.

I have mentioned it numerous time in my tutorials in the past. Here, I list all the major tweaks you can perform with this tool.

I have used Ubuntu here but the steps should be applicable to any Linux distribution using GNOME desktop environment.

Hubert Figuiere on Flatpak and Flathub, GLib 2.63.1 Coming Soon

  • Getting a stack trace out of a Flatpak

    So, the flatpak application you use just crashed

    How do you report it? If you file a bug just saying it crashed, the developers will probably ask for some stack trace. On Fedora 30, for example, abrt (the crash reporting system) doesn't provide any useful information. Let's see if we can extract that information.

    We are gonna have to use the terminal to use some command line tools. Flatpak has a tool flatpak-coredumpctl to use the core dump in the flatpak sandbox. The core dump is an image of the program memory when it crashed that will contain a lot about the crash. But by default the tool will not be able to provide much useful info. There is some initial setup need to be able to have a better output.

    First you must make sure that you have the right Debug package for the right version of the Flatpak runtime. Well, actually, for the corresponding SDK.

  • Music, Flathub and Qt

    I quickly realised that trying these apps on my Dell XPS 13 was really an adventure, mostly because of HiDPI (the high DPI screen that the PS 13 has). Lot of the applications found on Fedora, by default, don't support high DPI and a thus quasi impossible to use out of the box. Some of it is fixable easily, some of it with a bit more effort and some, we need to try harder.

    Almost all the apps I have tried used Qt. With Qt5 the fix is easy, albeit not necessarily user friendly. Just set the QT_AUTO_SCREEN_SCALE_FACTOR environment variable to 1 as specified in Qt HiDPI support documentation. There is also an API to set the attribute on the QCoreApplication object. There must be a good reason why this opt-in and not opt-out.

    [...]

    In the end, I have Hydrogen available on Flathub, the three others in queue for Flathub, and all have had patches submitted (with Muse3 and Rosegarden already merged upstream).

  • g_warning_once() in GLib 2.63.1

    GLib 2.63.1 will be released in the next few weeks, and will contain a fun new API to slightly simplify emitting a warning once, and then shutting up to avoid emitting loads of log spam.

Cast To TV v11 GNOME Chromecast Extension Adds Remote Widget Playlist, GNOME Shell 3.34 Support

Filed under
GNOME

Cast to TV, a GNOME Shell extension to cast media (with optional transcoding) to Chromecast and other devices over the local network, was updated to version 11 yesterday. This release brings support for the latest GNOME 3.34, a file queue (playlist) for the remote widget, NVENC hardware acceleration support, and more.

Cast to TV is a GNOME Shell extension to cast videos, music and pictures to Chromecast or other devices over a local network. It supports video transcoding on the fly (for videos that can't directly play on the device), customizable subtitles, it can show a music visualizer while casting music, and much more. For controlling the device, the Gnome Shell extensions adds a new button on the top panel with playback controls.

Filed under
GNOME

There weren't out in time for yesterday's formal GNOME 3.34.1 point release, but GNOME Shell and Mutter have out their prominent point releases today that are exciting on the correction front.

GNOME Shell 3.34.1 is heavy on the fixes. Prominent work there includes allowing the editing of app folder names, making menu animations more consistent, improving performance when enabling/disabling all extensions, fixing screen dimming on idle, crash fixes, and a variety of animation fixes. There is also the code for Wayland fullscreen compositing bypass and other fixes.

David Edmundson Improving KDE Plasma and GNOME's Tobias Mueller Speaks in ARES 2019

  • Improving Plasma’s Rendering (Part 1/2)

    Many parts of Plasma are powered by QtQuick, an easy to use API to render shapes/text/buttons etc.
    QtQuick contains a rendering engine powered by OpenGL making full use of the graphics card keeping our drawing super fast, super lightweight and in general amazing…when things work.

  • Tobias Mueller: Talking at ARES 2019 in Canterbury, UK

    The opening keynote was given by Alistair MacWilson from Bletchley Park. Yeah, the same Bletchley Park which Alan Turing worked at. He talked about the importance of academia in closing the cybersecurity talent gap. He said that the deficit of people knowing anything about cybersecurity skills is 3.3M with 380k alone in Europe, but APAC being desperately short of 2.1M professionals. All that is good news for us youngsters in the business, but not so good, he said, if you rely on the security of your IT infrastructure… It’s not getting any better, he said, considering that the number of connected devices and the complexity of our infrastructure is rising. You might think, he said, that highly technical skills are required to perform cybersecurity tasks. But he mentioned that 88% of the security problems that the global 5000 companies have stem from human factors. Inadequate and unfocussed training paired with insufficient resources contribute to that problem, he said. So if you don’t get continuous training then you will fall behind with your skill-set.

    There were many remarkable talks and the papers can be found online; albeit behind a paywall. But I expect SciHub to have copies and authors to be willing to share their work if you ask. Anyway, one talk I remember was about delivering Value Added Services to electric vehicle charging. They said that it is currently not very attractive for commercial operators to provide charging stations, because the margin is low. Hence, additional monetisation in form of Value Added Services (VAS) could be added. They were thinking of updating the software of the vehicle while it is charging. I am not convinced that updating the car’s firmware makes a good VAS but I’m not an economist and what do I know about the world of electric vehicles. Anyway, their proposal to add VAS to the communication protocol might be justified, but their scenario of delivering software updates over that channel seems like a lost opportunity to me. Software updates are currently the most successful approach to protecting users, so it seems warranted to have an update protocol rather than a VAS protocol for electric vehicles.

Dash to Dock v67 Released, Adds Unity-style ‘Trash’ Icon

Filed under
GNOME

Dash to Dock v67 adds support for the recently released GNOME 3.34. This change wasn’t trivial and is said to have necessitated “significant modernization of the code base”.

As a side effect, Dash to Dock developer Michele G says support for previous GNOME Shell versions has been dropped with this version.

Don’t panic unnecessarily though as older versions of Dash to Dock are still available to install from extensions.gnome.org (EGO) for previous GNOME Shell releases.

ArcMenu 33 Lands with HUGE Improvements, GNOME 3.34 Support

Filed under
GNOME

So when a bunch of you mailed in to to tell me there was new release (appreciated, btw!) I just had to check it out and give it a bit of a write-up here.

And what a release it is!

ArcMenu 33 (labelled as v34 on EGO) is a pretty substantial update packed full of welcome improvements — so much so that the app menu’s developers bill this update as a milestone release.

So what’s new?

Arc Menu now lets you select from a number of different menu layouts, including those more akin to Windows as well as those more akin to launchers found on DEs, such as Unity dash, Linux Mint’s Cinnamon menu, and the Solus OS Brisk Menu.
