I have an idea: Anyone experiencing this crash reliably, please help us to find its root cause by editing your /etc/environment and adding a line:
MUTTER_SYNC=1 and then reboot. Then next time a crash happens please tell us (here) the bug ID or error URL of the new crash. ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Incomplete ** Changed in: mutter (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886059 Title: gnome-shell crashed with assertion failure "!xcb_xlib_threads_sequence_lost" [xcb_io.c:260] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1886059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
