The comments below apply to the MIT servers for both R3 and R4.

Make sure that

- /dev/cgfour0 exists
- /dev/fb exists
- /dev/bwtwo0 does not exist
- /dev/bwtwo1 does not exist

Do not give a -dev option to the server.

Now to check: run xdpyinfo and it should report two screens.

Under R4, screen 0 should be your color screen: an 8-bit screen with
six visuals available, one of each type.  Screen 1 should be a 1-bit
StaticGray screen; that's your mono screen.

Under R3, screen 0 should be a 1-bit StaticGray screen and screen 1
should be an 8-bit PseudoColor screen.

(If you can't get xdpyinfo to list both screens, you haven't a hope of
actually *seeing* the mono screen.)

To see the other screen, you just have to get the mouse on it somehow.
The simple thing to do is to ensure you did not give the -zaphod option
to the server (R3 servers don't even have -zaphod, I think), and then
move the mouse off the left or right edge of the color screen.
Programmatically, you can XWarpPointer to a position on the desired
screen and it should flip to that screen (I have a program that allows
you do this, if you want it).

(Actually, the 1-bit screen *should* be a PseudoColor screen; that's
what the hardware is.  But StaticGray was easier, no doubt.)
