VM fails to reach user session after dist upgrade from focal to jammy

[Olivier Tilloy]

I just verified that bug #1951096 is fixed by dist-upgrading a fully up-to-date focal amd64 VM to jammy, but after rebooting I'm getting a completely blank (aubergine) screen, and I cannot even switch to a VT using the usual key combinations (Host+F<n> in VirtualBox).

Fortunately that VM had an ssh server running so I was able to ssh into it and get the system journal, which I'm attaching here.
I'm also attaching the dist-upgrade log in case it's useful, and I can provide more info if needed (I'll keep a snapshot of the VM in that broken state).

I upgraded a focal vm to jammy today and was unable to recreate this issue. I see the desktop when choosing either a wayland session or an xorg session.

I can still reproduce in that same focal VM, fully up-to-date, when dist-upgrading it to jammy.
I wonder if this has to do with the fact that it's configured for auto-login.
I'll have to test again in a brand new focal VM.

Just tested again in a brand new and fully up-to-date focal VM that I installed from the 20.04.3 desktop iso, then dist-upgraded to jammy, and I am not seeing the problem.

If it's reproducible only in that specific VM that has auto-login enabled, and probably other cruft, I think the bug can be safely closed.
