Problems with X window system

["ManuP" <Web-Zocker@gmx.de>]

Hi!

I just installed Debian 3.0 from CD.
Because I only had a text-based system, I typed apt-get install kde (or
kde2, don't know).
Because kde requires X, I thougt it would be installed with kde. It
was, but doesn't work.

When I type kde2 or startkde i get:

#x set root: unable to oben display
#ksplash: cannot connect to X server
#Aborting. $DISPLAY is not set
#ksmserver: cannot connect to X server
#connect() faild: connection refused

and when I type startx:

#/usr/X11R6/lib/X11/xinit/xserverrc: /usr/bin/X: No such file or
directory and some similiar code.

What's wrong?
I persume, I have to find "X" and save the path in
"/usr/X11R6/lib/X11/xinit/xserverrc".
But where is "X"?

kind regards,
ManuP
