    Phoronix: GNOME 3.32 Will Do A Better Job Picking The Primary GPU - Helping Out USB Displays, Etc

    The work around better GPU/infrastructure handling for GNOME 3.32 continues with the most recent work merged this weekend being for better handling by Mutter over deciding the primary GPU of the system in multi-GPU systems whether it be multiple graphics cards, notebooks with dual GPUs, or systems with a USB-based external display adapter...

    Maybe while their at it. Gnome can start launching games on my primary display and not a portrait secondary display.

    Anyone with the issue can fix it per session with display properties, selects single display, when the confirm dialog comes up. Hit revert settings.

    Games will launch correctly until you reboot.

      Does DisplayLink 3 still not work with Linux? Or has there been progress... ?

        Outside of dosbox games trying to run on both monitors at the same time, half a screen on each. I didn't notice many instances of games running on my second gpu with Gnome.
        Kde-Neon on the other hand consistently runs games through the secondary card mainly Vulkan games. FPS lost doing so was anywhere from 7-20 depending on the game.

        I fixed the problem by removing the second gpu from the system.

          Is there anyway to launch application on focused monitor?

            At this point Gnome is the only DE that actually works with everything.

            It reports Logitech Unifying devices' battery life.
            It works flawlessly under Wayland (Plasma Wayland immediately locks up under Nouveau)
            Its Wayland compositor is by far the most complete and functional and handles multi-display setups amazingly well
            It's the only compositor to work with Pipewire for desktop recording under Wayland (badly, but at least it WORKS.)

            And so on.

            Hopefully we can finally get some standardization on a de facto Linux Wayland desktop environment for other DEs to follow and emulate.

              In the meantime you could ask devilspie2 to launch ALL windows or the specific games on the desired monitor with some .lua config files ~/.config/devilspie2/

                Sonadow Tend to agree. Moving to Wayland compositors is extremely costly. Not because of Wayland but because of all the compositor specifc extras that come on top.

                Someone really need to revisit the current level of fragmentation. We can’t do as many DEs as we move from x11 window managers to Wayland compositors.

                  There's already plenty collaboration between DE's. Having different UX views on Linux is a good thing as long as technical details are agreed upon regardless of UX.

                    nanonyme There is not much to agree upon when each DE try do their own compositor on top of Wayland.
