Hi, Luc
Nope, you can't run more than 256 colors with the standard GRASS xdriver. 
However, some kind soul (I can't recall who!) wrote a version of xdriver 
that will display a GRASS 256-color monitor window on a 24-bit display. I 
can arrange for you to ftp the source code from me if you'd like; drop me 
a note directly (if anyone else needs this, let me know too). I've used 
it quite successfully on both Sun 24-bit displays, and 24-bit xterm 
emulation software (Hummingbird's eXceedNT, Intergraph's eXalt). 
Hopefully your upgrade won't be wasted! (Just don't expect any benefits 
for GRASS :(  )
