Description whoopsdecade 2019-05-07 15:32:49 UTC

SUMMARY
Logging in and out of a session while leaving a second one "locked" creates a bunch of "unused" sessions.

STEPS TO REPRODUCE
1. Login to account A and switch users (should stay in background
2. Log in to account B and then log out
3. Open account A once again and switch users, you will see an "unused" session in the menu.
4. Repeat the same process N times and you will get N "unused" sessions.

OBSERVED RESULT

This was fixed in Plasma 5.15.

Unused sessions

It's not resolved yet. This screenshot is from today on Plasma 5.15.5. I've also had it happen several times before. It eventually cleans up but it's not predictable.. and if I select one of the "unused" sessions the session might never log the second user in (remains loading the desktop, blank screen) and I have to use the hotkey to get back to the first user and kill the other users processes.

Comment 3 whoopsdecade 2019-07-17 13:08:52 UTC

Sometimes when I try to go back to the previous user the screen just stays blank, no login occurs and it just hangs there and I have to force-restart my machine. Changing user sessions is basic guys and it has always been very unreliable in Plasma, you need to figure this out.

Comment 4 61.1p57 2019-09-18 09:12:13 UTC

FWIW, I see a geoclue agent process running even after I called `loginctl terminate-user`. The unused session goes away when I kill that process.

I can confirm now.

This is actually a duplicate of Bug 355920 instead, which turned out to be an SDDM issue which was fixed in version 0.19.
