I've got grass running on through a monochrome NCD x-terminal (circa
1992). Everything I've tried so far works fine, except for displaying
rasters. They just come back as black, even if the color table is set to
all white.
d.mon start=x0 reports:
using default visual which is StaticGray
ncolors: 2
Graphics driver [x0] started
d.vect, d.sites, d.text, and d.barscale all work as expected, as long as
I choose a light color.
But d.rast and friends won't output in any color but black.
What does seem to work is:
d.erase color=white
d.rast -o roads
but it working in negatives gets confusing very quickly and doesn't work
all that well......

any ideas or experience?
The display library always reserves colour zero for NULL, so you will
only have one level of grey for all of the non-NULL values.
It appears that there are a couple of bugs which could affect
the situation; however, I'm not sure whether fixing them would gain
you anything.
