Played around even more. If I set "su -c 'env DISPLAY=:0 DRI_PRIME=1 glxinfo' my_username >/dev/null" as a post-suspend hook in systemd, my GPU returns to state 1 after resume. It would be better to set this hook in KDE, so I don't have to jump through hooks to run in on the X server / with the correct authentication cookie, but I couldn't find a way to do that. I guess this could much rather be done from the kernel, but I am not familiar with nouveau source code at all to write a patch.
Resuming from hibernation, on the other hand, is completely broken and leads to a lockup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803179 Title: System does not reliably come out of suspend To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1803179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
