Number of Colors Displayed

Greg Koerper from US EPA Environmental Research Lab wrote on May 6 that Grass
is not displaying 256 colors on his monitor. I have the same problem on my
SPARC10 using XDRIVE. Running Grass4.1, I displayed a LANDSAT image. When
I use xv utility to grab the grass image, xv reports 8 colors.
Can anyone help me to have GRASS display 256 colors?
