Tested on Dell XPS13 (Intel GPU) and Precision M3800 (Intel/Nvidia-nouveau), with evdi-backed displays mostly focusing on enabling/disabling screens, both by system settings as well as ACPI events (lid closing/opening). Looks fine so far.

Any DRM driver that may temporarily fail drmModePageFlip() calls might trigger this. [ Test case ] I triggered the freeze particularly by trying to make a DisplayLink output the only active output via GNOME display settings. Other triggers are possible. This fix may help with https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1853357 but I don't know for sure. [ Regression potential ] Higher page flips could happen using native backend (wayland) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1874818/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
