Basically this means that something else stole all of the colors
available for your display. Two ways out:

a) I think this only happens with 256-color (8bit) X servers. Set up
   your X server for 16 bit color depth or better.

b) remove application that use many colors. The background image or
   Netscape are likely culprits, but also the smoothly colored little
   Gnome icons are troublesome. KDE might be better in this regard
   according to what I've gathered.

Also, you might try taking the hint in that error message, e.g.:

c) x11(colortype="gray");demo(graphics)
