Unfortunately the link in comment #5 is the crash reporting tool crashing. Reviewing the list of all crash reports from the same machine shows no shell crashes since April 2021.
Please try removing any extensions you might have: cd ~/.local/share/gnome-shell/ rm -rf extensions and then log in again. If the bug still occurs after that then next time it happens please run: journalctl -b0 > journal.txt and attach the resulting text file here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1987228 Title: Bug display when turning to hibernation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1987228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
