I'm not able to find out what exactly is causing the problem (google
tells me that everyone is puzzled by that).

Still I have found a solution/work around.

Just add this line to /etc/X11/xdm/xdm-config:
DisplayManager*authName: MIT-MAGIC-COOKIE-1

This way the MIT-MAGIC-COOKIE-1 will be used as the authorization key
instead of the XDM-AUTHORIZATION-1 key, which seems to be causing the

After that the issue disappears.

I found the solution here:
