Below seems to be the only gnome-shell crash and it's an odd one. Even though it's a Wayland session the cause was some unhandled X11 error coming from the X server (Xwayland). This isn't totally surprising if Teams is another Electron client and Electron (Chromium) defaults to X11 instead of native Wayland.
To debug this further please add MUTTER_SYNC=1 to /etc/environment, reboot, and then report new crashes when they happen. avril 01 13:34:24 LH33976 gnome-shell[4799]: Received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 7457903 error_code 3 request_code 7 (core protocol) minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the MUTTER_SYNC environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the mtk_x_error() function.) avril 01 13:34:24 LH33976 gnome-shell[4799]: GNOME Shell crashed with signal 5 avril 01 13:34:24 LH33976 gnome-shell[5458]: (EE) failed to read Wayland events: Connection reset by peer ** Package changed: gnome-shell (Ubuntu) => mutter (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2106656 Title: Shell crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106656/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
