Folks,
I am trying to configure X windows on my Osborne system.  Has anyone got it 
working on the following or similar configuration ?  I would appreciate any 
advice that may be available, especially if it includes a working XF86config!

At the moment, calling X withthe command 'startx' I get a blank white screen 
with no cursor, mouse indicator, etc.  All I can do is Alt-Ctrl-backspace to 
exit.  I have spent some time trying various permutations and obtaining 
information from the manufacturer and other sources.

If someone is able to help me here, I'd be very grateful.  If appropriate, 
please email-me direct rather than post to any news-group.

Regards and thanks in advance, David Marriott

The system is a standard configuration as released by Osborne in mid-1995, 
before they went under and were subsequently taken over by Gateway 2000.
