After a login a get presented a screen with 3 sessions: "bla", "default" and "bla2" (the screen where you select if you want to use "gnome/kde/xfce". I do not know how to get rid of this screen. I would suspect simply a "logout" in XFCE but this does not change anything. Then i am back in the login screen and the "last accessed" date is not even updated of the session i just restored.
So i suspect a bug.

I am using Fedora.
