Great! By the way, one possible reason why you were unable to follow comment #2 is that gdm is designed to catch mutter/gnome-shell crashes in the Wayland backend (which it tries first). If such a crash occurs then it is meant to automatically fall back to Xorg.
Regardless of whether the automatic fallback was working for you, that crash handling done by gdm would possibly prevent any crash in mutter /gnome-shell Wayland start-up from being saved and sent to Ubuntu :( -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1826025 Title: gnome-shell trap int3 no desktop ("Impossible to lock surface front buffer: Function not implemented" on Matrox graphics card) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1826025/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
