[GRASS-user] problem whit raster images

[Wolfgang]

Hi,

usually during input the colors are getting separated into the "red", 
"green" and "blue" chanal (you can display these chanals as gray scale 
images). For displaying you could use:
  d.rgb red=map.red green=map.green blue=map.blue
An alternative is to merge them first:
  r.composite red=map.red green=map.green blue=map.blue output=map.rgb
  d.rast map.rgb
(replace 'map' with your map name)

the other problem ist probably due to the fact that you need an 
X-display, before you can display any maps! So try this:
  d.mon x0

I hope this helps you
Wolfgang
