Description Martin 2021-12-01 06:39:51 UTC 
SUMMARY
I've inadvertently tried to login twice with the same login name with 2 different sessions. The result is that the new session ends in a black screen the and first session is also blocked.


STEPS TO REPRODUCE
1. login
2. lock screen
3. create new session
4. login with same name

OBSERVED RESULT
Both sessions are unusable

EXPECTED RESULT
2 different working sessions with same login name or fallback to session 1.

I am also curious how this issue will evolve further.
Comment 2 Nate Graham 2023-05-17 17:16:38 UTC 
This is an SDDM configuration issue; make sure your SDDM config has ReuseSessions=true in it; or remove that line if it says false.
