We are currently running X11R3 on a Sun 4/260, with SunOS 4.0. 
Attached to it are two 19" *color* monitors.

I understand that the Xsun server is capable of handling both of these
displays. [At least, one as a black and white, and one as a color].

I have several questions:

1) How does one indicate to the Xsun server (via xinit) that there are other
monitors attached?  How is the /dev/cgtwo1 <--> unix:0.1 association made?

2)

2) Is only one window manager needed for the control of both displays?  If
so, then is it possible for a window to be dragged across the displays, or
a window to straddle the displays? Why or why not?

3) Our application requires us to have three displays attatched to our
machine, are there any limitations in the design of the server to preclude
such support?  Why is there a limitation on the Xsun server of only 1 B&W 
and 1 Color display?  Does 3 monitor support require server modification? 
And if so, what changes are needed?

4) Does anyone know what support the to-be-released X11/NeWS server will
have for multiple displays?


Thanks in advance
