After removing all extensions I can at least log in to a Xorg session. But you get logged into the Activities Overview as expected. Clicking on the desktop then triggers the crash "Oh no!".
So it seems the issue is something to do with the vanilla GNOME desktop. We only see the bug sooner when Ubuntu Dock is loaded because that starts on the desktop. ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => High -- 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/1952556 Title: Jammy, attempt to log into Xorg session, "Oh no! Something has gone wrong." Status in gnome-shell package in Ubuntu: Confirmed Bug description: On Jammy, I log out of a Wayland session, click my name on the login screen, go down to the options menu and select Ubuntu on Xorg, enter my password, get "Oh no! Something has gone wrong. A probleme has occurred and the system can't recover. Please log out and try again. [Log Out]" I click the log out button and log in again, and I'm logged into a Wayland session. Why was I logged into a Wayland session when I selected Xorg the last time I tried to log in? This issue is intermittent I had been able to log into an Xorg session just a few minutes prior.
