I have tried to reproduce this but I can't, not in a VM or on my real system (i915). I tried with and without automatic login, with the vanilla GNOME session and with the Ubuntu session, with and without the same user logged in over SSH (to keep the systemd --user instance alive), and every log in/out cycle worked. Sorry :/
I'll note that VT switching works for me on all machines, and I see no lingering processes after logging out. One thing I did manage to reproduce, using the attached program (a daemon which doesn't quit when SIGTERMed, which I was trying to use to recreate your situation. Run it from xterm *not* gnome-terminal), is a 30 second *delay* on logout. Did you wait longer than that? If I edit `/usr/lib/systemd/user/gnome-session-wayland.service` and add TimeoutStopSec=5 at the end (then reboot), then the delay reduces to 5 seconds. I'll ask upstream about whether that's a good idea but this might not be your problem. If you go to `/usr/share/wayland-sessions/`, you can remove `--systemd` from the `Exec=` line of the session you're using, to revert to the previous method of launching the session. If that fixes it, then (in the broken situation), please enable GDM debug output (/etc/gdm3/custom.conf), and while the system is hanging fetch the output of 'loginctl', then for each session listed there, 'loginctl show-session <session id>' and 'loginctl session-status <session-id>', as well as 'journalctl -b' and attach them here.
