    Phoronix: GNOME's Mutter On Wayland Will Now Support GPU Hot-Plugging

    GNOME's Mutter compositor native back-end will now deal with GPU hot-plugging at run-time and begin managing its display outputs...

    Great. Does this mean it will eventually support GPU recovery as well?

    (since GPU recovery is like disconnecting and then connecting the faulty GPU)

      Glad to see it's going. Hopefully better support for outputs attached to eGPU will be implemented too: https://www.reddit.com/r/linux_gamin...egpu_on_linux/

        Good, what about async input processing?

          So... will I be able to swap video cards, reboot, and continue as normal? Without reinstalling or fussing with the kernel?

            This has nothing to do with this. This is about hotplugging which has to do runtime reconfiguration without needing to restart.

              GPU recovery is something else entirely, it has to be supported by your GPU driver (eg. recent amdgpu claims to support it now)

                This is more about for example running a Thunderbolt eGPU with your laptop and being able to plug / unplug it when the computer is on and everything working smoothly. Something I really miss on linux, it works great with my mac but not at all on linux currently, and I really need to it be able to use Linux as my main work OS.

                  I am confused. Where is the problem with this? I have been doing it for years (though I have never tried with nVidia cards). This is more about doing it live (hence "hot"-plug), without the need for reboot in-between. Specifically aimed at external GPU enclosures.
