Thanks, for the suggestions!  Unfortunately I haven't gotten it to work yet.

what do you mean with "I use gdmflexiserver -n".  When I enable XDMCP and 
connect from a remote machine I get an empty X-Server desktop (with the 
X-mouse).  I'm sorry, but this is all new to me.

I don't need anything fancy, a primitive first approach was to setup an 
autologin from kdm, then run X11vnc from a sript so that I could connect from 
a remote computer.  It would work if I kept everything plugged in, but I'd 
like to just put the box an a shelf and run it from a laptop or whatever.
