It looks like there might be two different crashes here. Comment #2 looks like bug 1969422.
If there is indeed another crash happening here then please follow these instructions to find it: 1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Summary changed: - gnome-shell (Wayland) crashes when screen locker activates (jj) + gnome-shell (Wayland) crashes with SIGSEGV when screen locker activates (jj), immediately after meta_workspace_get_work_area_for_monitor: assertion 'logical_monitor != NULL' failed ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- 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/1987209 Title: gnome-shell (Wayland) crashes with SIGSEGV when screen locker activates (jj), immediately after meta_workspace_get_work_area_for_monitor: assertion 'logical_monitor != NULL' failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1987209/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
