How do I get rid of those white monitors?

Regarding the second problem first: You really _don't_ want to run more
than one monitor at a time on the same graphics monitor. Due to the
nature of the XDRIVER and Xwindows, they will be trying to reserve colors
for themselves and they will always be problematic. Instead, use d.frame
to break a single monitor up into multiple frames, each of which can be
displayed to individually.
Your first problem may be caused by having other graphics-intensive
windows open when you start your GRASS monitor; try limiting your windows
to only text-based windows. Also, make sure that you are running in
colormode fixed (d.colormode fixed; d.erase). Good luck!
