it's simple actually
First you have to tell the X server (the one with the screen attached
) that certain X clients are allowed to access it
xhost + //disables accesss control (allows everybody to connect to your X server)
for more finegrained control take a look at
http://www.csa.ru/~il/cgi-bin/man.cgi?topic=xhost Next go to another computer and start an X client (which is actually just an X application) like this
xclock -display IP_NUMBER_OF_XSERVER:0
that will display the 'xclock' application on the server's screen
