[SOLVED]XFCE - can't log out to switch user

[Clad in Sky]

, yet everything else works as expected. Hibernate, Suspend, Shut down, Restart all do what they are supposed to. But when I say log out I only get a black screen or more frequently only my desktop background is on the screen and a mouse pointer (movable) and the login manager does not show up like it used to.
Now, I did a world update yesterday (when the problem seems to have started), but of course I don't know which packages were updated.
I know udev was amongst them, if that is any help.

So, does anyone have any idea what the problem might be
or
can tell me how I start looking for the problem?

Thanks.

No ideas, hm?
I'll have to see if I can find anythig myself, then.


SOLVED: Seems like it's some sort of bug with lxdm. Installed lightdm and logging out works now.
