Jonathan, 1. If you have any gnome-shell extensions loaded then please uninstall them all, reboot, and tell us if that fixes the problem. If you don't know how then just go to step 2.
2. It sounds likely the gnome-shell process is crashing, so if the problem persists please log into a virtual terminal (Ctrl+Alt+F4 etc) and follow these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment --- Mark, In case you are experiencing a different problem (and it's likely you are), please log a separate bug if you have any more trouble by running: ubuntu-bug gdm3 ** Changed in: gdm3 (Ubuntu) Status: Confirmed => Incomplete ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Tags added: nvidia -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773386 Title: Returned to login screen immediately after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1773386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
