    In a multi-screen setup (in my case, one color and one b/w screen),
    is there a way for an application to cause the server to display
    a particular screen (instead of having to manually drag the cursor
    off the edges).

There's no way to tell from the protocol that screens are switched off
the same physical monitor.  The best you can probably do is to
explicitly warp the pointer to the desired screen.

I would like very much to display on multiple screens using one server.
The configuration is: Sparcstation running 4.0.3 with two framebuffers
(cgthree0 and cgsix0), MIT X with patches 1-14, and Motif 1.1. 
Seems as if it should be simple enough, the code in the XSun server 
appears as if it should handle it o.k..  The scenario is this: the
.xserverrc file says X :0 -dev /dev/cgthree0 -dev /dev/cgsix0
.xinitrc is starting two window managers mwm -display :0.0, mwm -display :0.1

The problem is that only one screen ever gets activates, it happens to be
whichever framebuffer is the first -dev passed to the server. As a point
of further information, the same setup mentioned above DOES activate both
screens if the server used happens to be xnews -- unfortunately my 
application doesn't work so well with that server.

Can anyone provide some words of wisdom about the correct way of using
multiple screens with XSun?  Thanks so much.
