Either side will work, it is circular.

If you wish to use only one screen, use the -dev option to Xsun.  I use

xinit xterm -C <xterm opts> -- X.cgfour -dev /dev/cgfour0 ; kbd_mode -a

The X.cgfour is necessary on our machines because all of the Purdue+
speedups to not work correctly on a cgfour, so we have a separate binary
for the cgfours.  You can, of course, replace /dev/cgfour0 with
/dev/bwtwo1 to use B&W only.  I like the colors, so I put up with the
slower performance.

A lot of work was done by Gene Spafford and Sam Kimery for the Purdue
speedups on B&W units because that is what they had at the time.
