well I have done, but none of these hints google gave me solved my problem. 
but as i found out it seems to be a problem with xorg and not with kde 
communication, i shall go to another list, asking there... 
despite you know how i can solve the access problem in a secure and easy to 
use way, any suggestion would be greatly appreciated. when i change the 
permissions of /root/.xauth... file so that the user can access it, everything 
works, but i do not think this is a good and intended way.
