i have kde.i can run k3b as user.
when i login as root in the same konsole run run k3b but there is a display problem.


now to run as root.

NOTE: IF I GO TO ROOT KDE IT IS WORKING WELL.(THE PROBLEM ONLY IN THE USER AREA)

-------------THANKS.

I think it is the problem of xhost blocking access of root to the server. It is for security reason I think. Try running

as a normal user before "su -".

If this doesn't work, try to look for the usage of xhost from the man pages or from this forums or from the Internet. I don't remember the exact option to disable xhost from blocking access.

Good luck.
