I tried (just now) deliberately leaving it longer than 30 seconds to come back after a logout. In fact left it longer than 60 seconds. Nothing happening. I wasn't logged in via ssh as well at the time (I hadn't thought the systemd --user instance was related to the ssh session before so presumably might be confusing matters) so there's nothing more to report than that the screen remained resolutely black.
There is no /usr/lib/systemd/user/gnome-session-wayland.service file on this system. There is a .target file though which is presumably the one. As the presumably-default timeout didn't seem to be honoured here there didn't seem a lot of point in adding a shorter one so I left the file alone. I'll try the change to /usr/share/wayland-sessions/ubuntu- wayland.desktop (the only file in that directory) and report back in the next comment... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1841915 Title: black screen, unresponsive, after logout from gnome Wayland session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1841915/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
