Something different happened tonight, but it feels related so I'm going to post it with this bug report.
Tonight I did an apt upgrade for a single package -- containerd. Gnome didn't crash this time, but a short time later I noticed that /var/log/syslog was filling up with the following messages: Mar 17 20:35:29 scruffy gnome-shell[9529]: Object St.Bin (0x5558975eac80), has been already deallocated — impossible to set any property on it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs. Mar 17 20:35:29 scruffy gnome-shell[9529]: == Stack trace for context 0x555888e95220 == Mar 17 20:35:29 scruffy gnome-shell[9529]: #0 7ffddf081900 I /usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/docking.js:2051 (1ee0192a1240 @ 208) These 3 lines were being repeated dozens of times a second, and started at the same time I did the upgrade. I didn't know how else to stop them so I rebooted. After rebooting the system seems fine again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915481 Title: [nvidia] gnome crashes with Fatal IO errors (lost connection to Xorg) after running `apt upgrade` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1915481/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
