It looks like you can't login again after a logout on Gnome (with Xorg in my case) because the session is not properly closed / something hangs. The bug might be even older, but I didn't use Gnome prior to Ubuntu 18.04.ĭisplay Manager related: How To Change The Default Display Manager (Switch To GDM, LightDM, SDDM, Or LXDM) In Debian, Ubuntu Or Linux Mint I've experienced this bug with Ubuntu 18.04, 18.10 19.04, so it's not new, but it seems to have escaped the developers.

It also worth noting that this happens with both a single user (having only one user on the system), and on systems with multiple users, regardless if you try to login using the same user, or switch to a different user. That might be a different issue though, that's why I only mentioned Ubuntu in the title, but you can try this on any Linux distribution.

And it's not just Ubuntu, as I have seen reports with the same issue for Fedora too (it's marked as fixed, though there are still users looking for a solution), but oddly it seems to happen with Wayland, and not Xorg, which is what my computer uses when running into this.
