Since you said in comment #18 when it happened again, and your log shows upstream issue mutter#1516 happened around that time, I am going to assume that's the problem and will link it to https://gitlab.gnome.org/GNOME/mutter/-/issues/1516
However, to be sure we're not looking at the wrong problem, please next time: 1. Confirm the exact time of day the problem occurred; and 2. Check for crashes using these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment ** Package changed: gnome-shell (Ubuntu) => mutter (Ubuntu) ** No longer affects: gnome-shell-extension-ubuntu-dock (Ubuntu) ** Summary changed: - [nvidia] gnome-shell freezes randomly after upgrading to groovy + [nvidia] gnome-shell freezes randomly ** Also affects: mutter via https://gitlab.gnome.org/GNOME/mutter/-/issues/1516 Importance: Unknown Status: Unknown ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- 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/1912246 Title: [nvidia] gnome-shell freezes randomly To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1912246/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
