You cannot run programs that require an X server, until you have started the X server that they are going to use. You can start X without running KDE. It will take some fiddling with X startup scripts to make that possible. Start by looking at startx, possibly located in
/usr/X11R6/bin. Or, it may be as simple as
Code:
X
DISPLAY=0.0 yourProgramThatUsesX
--- rod.
