I’ve been using SDDM and it doesn’t seems to play nice with XFCE:
When two users are logged and one clicks “End Session”, it shows a black screen with a lock saying “This session is locked. You will be redirected to a login screen” then it takes immediately to the other user’s session without ever asking for a password.
Another question, is there any way to have SDDM show a login screen after you resume when the laptop is on suspend?
EDIT: Back to LightDM which is working fine now. SDDM doesn’t fit my needs, sadly.
