X driver

[Paul Koch]

I'm just getting started with GRASS, running it on an HP.  It was 
installed by a techie who has since left.  I am following the Leicester 
tutorial online.  In response to 

GRASS-GRID > d.mon start=x0

I am getting the following message:

Error:  could not execute '/users/grass/driver/XDRIVER'
Please start graphics monitor <x0>.
Error - Graphics monitor <x0> not running!

The /driver subdirectory is empty and I'd like to avoid downloading all 
the source files to find a solution.  What's the best way to get past 
this error?

Thanks in advance to anyone who can help.
