Here is a log with a few crashes. It seems to always come after a few of these:
Mar 6 01:24:57 wolfenstein rtkit-daemon[1197]: Supervising 9 threads of 5 processes of 1 users. Mar 6 01:30:29 wolfenstein rtkit-daemon[1197]: message repeated 19 times: [ Supervising 9 threads of 5 processes of 1 users.] Mar 6 01:30:29 wolfenstein rtkit-daemon[1197]: Successfully made thread 122522 of process 122427 owned by '1000' RT at priority 10. The log lacks the last crash (~19:20) since I attached gdb to the running gnome-shell process but couldn't switch back to the console gdb was started from (frozen screen, but I could hear the video was still playing). Will try attaching through ssh from another computer next time. ** Attachment added: "log.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1866222/+attachment/5334373/+files/log.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1866222 Title: GNOME Shell crashed with signal 11 Status in gnome-shell package in Ubuntu: Incomplete Bug description: gnome-shell has crashed twice on me today. Unfortunately there's nothing in /var/crash. There's nothing in the journalctl log prior to the crash that explains it. I've attached a log of everything between when the crash happened and when I logged back in (though I suspect most of it is not relevant).
