Thanks for the bug report. I don't think the above log messages are relevant to the main problem here. Please start by removing all local extensions:
cd ~/.local/share/gnome-shell/ rm -rf extensions and then log in again. If the problem continues to happen then next time it does, after bringing the machine back to life (without rebooting), please run: journalctl -b0 > journal.txt and attach the resulting text file here. ** 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/2075350 Title: gnome-shell seems to hang on monitor disconnect, killing gnome-shell process helps to bring system to life To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2075350/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
