I was able to capture a journalctl logs for a *successful* shutdown. In this log, I see the same GDM error:
gdm.service: Main process exited, code=exited, status=1/FAILURE gdm.service: Failed with result 'exit-code' Therefore, I must conclude that GDM is not the culprit in the shutdown problem reported in this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926816 Title: Computer does not shut down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1926816/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
