probleme opening monitors

Hey everybody!
I've already got another probleme: I can't open any monitors.
I'm working on a PC, not connected to any network and with linux installed
just now to work with GRASS.
Here's the message I get when trying to start the monitors (d.mon):

----------------------------------------------------------------------------

Problem selecting x0. Will try once more

Please start graphics monitor <x0>.

Thanks a lot if you could help

You are using a 24-bit X server with an 8-bit GRASS Monitor.
Try using the XDRIVER24 program instead. If you change etc/monitorcap,
things will work.

Good luck.

This message generally occurs when you use XDRIVER with a X-windows
server in true color (16 or 24 bits)... You have two choices :
  - use a 256 color X-windows server (and have a bigger
  logical screen size...
  - use XDRIVER24 instead of XDRIVER (better solution, works
  with all X11 color models

BTW, another question : why still distribute XDRIVER ? Looking at
sources, XDRIVER24 is just an enhancement of XDRIVER, and may be
considered as the current version... another thing to clean...

Perhaps your problems comes from the configuration of your monitor (Pc´s
monitor). GRASS works with 8 bits colormap, and if you have a monitor
with an higher resolution (16 bits, or 24 bits), GRASS can't open his
display monitor. Try to configurate your monitor resolution with
Xconfigurator in Linux. Choose an 8 bits resolution, so open startx and
try to open one GRASS monitor display.

Try it and tell me if it works.
