XDMCP forwarding

[rwk at americom.com]

Gary,

I had better explain muself in more detail...

I want to run MS-Windows XP with a third party X-server.  However, I
have been running Unix so long, that I cannot adapt to the "click to
type" requirement which the Windows window manager requires.

Therefore, I need to run an X desktop (like gdm) which takes over the
whole screen and acts just like my machine at work (but then I have
Windows underneath when I need to run Windows programs).

I don't understand what you you mean by:

  "start windows on you local host without a window manager, then ssh
   over to the remote, be sure DISPLAY is set and working, then start
   the remote window manager.

What I want to run is gdm (a display manager).  Are you saying I should
forget that and run a a "window manager" directly (without a "desktop
manager")?  Or are you saying I can run gdm in a way that skips the
login screen?

It sounds hopeful and your help is greatly appreciated!  I have spent
many hours trying to get this to work.

Best regards,
Dick
