You don't say if this is local or remote.
If remote, remember to use -Y, ie:

$ ssh -Y myserver

If it is local, use sudo for commands that need to be run as root. That 
will preserve your Xwindows permissions.  However, runing KDE based 
applications via sudo, will create (recreate) ~/.ICEauthority as root.  
This will cause your next login to fail.  Be sure to remove (or change 
permissions on) it before you log out.

Also, most of the system-config-* commands are now able to ask for the 
root password, thus enabling you to run them from the command line 
either locally or remote as yourself.


Good luck!
