Hi Roland,

have you seen what's mentioned here: 
http://developer.berlios.de/bugs/?func=detailbug&bug_id=18258&group_id=2978

Wether it helps or not, it would be great to see the server side of this, so please post the corresponding entries of your /var/log/syslog after configuring the x2goserver for debugging(set it in /etc/x2go/x2goserver.conf). 

Nevertheless, the only Cookies I can think used by x2go are the MIT magic cookies of X... maybe try to delete the .Xauthority of the user trying to log in and retry...

Greetings,
@Kjellski

I must have read every mailing list and other posts I could find on
Google regarding this problem.  Nowhere was anyone able to identify
the actual cause and fix for this problem.

How can this be?  Does anyone know where the X2Go developer(s) hang out?

thanks
