    Phoronix: GNOME Work Moving Ahead On Deep Color Support, Triple Buffering

    It's been a while since having any major break-through changes to talk about for GNOME contributed by Canonical's prolific developer Daniel Van Vugt, but he's been at the grind making progress on some big ticket items...

    Great stuff by vanvugt as always. It’s probably not ready for upstream review yet.

    Same weekly reports also show good work on GNOME by other Canonical employees. Gone are the days of NIH and CLA.

      Something that bugged me for a while was the not matching primary display configuration between Wayland and Xwayland resulting on X apps starting on the wrong screen. A PR for it came a few days ago, of course it has to be reviewed but merged for Gnome 40 should look good.

        Is Deep Color the same as HDR? How is the HDR story on Linux anyway, can I experience HDR content on Linux (via video files, streaming or games) assuming I have a compatible display?

              Not really, but they're related and one is necessary for the other. Deep Color allows for more than 8-bit per channel color and came with the HDMI 1.3 spec. High end 1080p TVs in the PS3 era had Deep Color. It's basically more HDMI bandwidth and color space. HDR, actual UHD spec HDR, is 10-bit color depth, wide color gamut, with brightness and contrast standards (and more) and came with HDMI 2.1...or one of the 2.0 subsets...

              I don't really know the actual specifics and numbers of DC/HDR outside of that basic grasp of what they are, but I know that Deep Color is one of the big milestones on the way to HDR10/UHD/??? they want to call it. Everyone having their own buzzword gets old and confusing.

              And the HDR story is basically this article and some older Phoronix articles about what they're working on. I have a 4K HDR TV that I'm using to post from Fedora. Unless things change soon, be prepared to dual-boot with Windows if you want to experience HDR content.

                Very advanced. Does it do simple stuff yet? Does it have window buttons without an extension? Can it do tiling without an extension? Has it stopped breaking the important extensions with every point release?

                  Now the Marge Bot merged herself \o/
                  https://gitlab.gnome.org/GNOME/mutte..._requests/1549

                  It’s pretty similar to the freedesktop merge bot. This is very useful because the maintainers can barely keep up with the many many MRs.
