There are several ways around this - the cleanest one being to use (in  KDE) 
kdesu e.g. `kdesu xterm` which will prompt for the root password and then run 
the program.

Another solution is to (partially) disable access control to the screen using 
the xhost command, e.g.`xhost +localhost` allows any local process access to 
the screen regardless of the user.

The third way to open a window as a different user is to provide access to 
that specific user using the xauth command - your supposed to use it to 
export and import specific entries from you .Xauthority file, but a quicker 
solution is to just copy the .Xauthority file from the home directory of the 
current user to that of the user you want to run the program as.

There's probably other ways too.
