Sorry I haven't got back to investigating this yet. I wonder though if it's related to:
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/690 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1841915 Title: black screen, unresponsive, after logout from gnome Wayland session Status in gdm3 package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: on logout the screen is black, the system is unresponsive and has to be restarted. (Untested by me yet, but I expect ssh-ing in and restarting gdm would work.) I believe this may be already reported upstream here: https://bugzilla.redhat.com/show_bug.cgi?id=1745554 That's why I've reported this against gdm3 even though I honestly don't know if it might be a gnome-shell, gnome-session or mutter based error. (FWIW without the upstream bug to link to I'd maybe suspect gnome-shell first.) NB: This machine's conf has AutomaticLogin enabled, but another machine also on 19.10 does not, and it's showing the same thing. On *this* machine I found that the *first* time I logged out, it was OK, but not the second time. On the other machine, it fails first time too. It's as if the gdm login screen can appear exactly once. That (and being on gnome 3.33) is why I don't think this is a dupe of #1824588. Nothing appears in /var/crash as a result of this.
