We are running X11/R3 on a Sun3/60 with a color monitor.  We can run X
in color mode by starting with 'xinit -- -dev /dev/cgfour'.  The default
appears to be black and white.

We have observed the documented (XSun man page) two screen problem (feature)
where moving the cursor off the left or right edge of the workspace 
reveals a new (blank) screen.

We have two requests: (1) can we either make use of this hidden screen, 
doubling our workspace (I understand one is color, the other is black and
white), or can we prevent the wrap effect which is very disconcerting
for the user whose display goes blank every time his curser slips off the
edge.

(2) How can we tell xdm we want to use color mode.  xdm does not recognize
the '--' notation understood by xinit, nor a -dev option.  Also, we would
like to be able to switch between color/bw between sessions rather than have 
to kill xdm first.  Since the color implementation is
so slow as to be unusable under most circumstances, we only want to go
into color mode to experiment with certain research problems.

A related question is, will these problems all go away with R4.  We are 
currently upgrading to R4 and are under the impression that color under
R4 does not have R3's serious performance problems.
