GRASS graphics driver can't set color

[James Harper]

It sounds as if you might be starting X windows as Root.  Log in as another
user (not a root user) and then go into X windows and start the monitor.
For some reason X windows will not support 8bit color when logged on as
Root.  I am assuming that you have already setup the monitors using via
monitorcap file and set mknod/chmod to the fifo devices.  If not it is
really easy to do and if you like I will give you detailed instructions on
how to set them up.

Hello,

We have problems installing GRASS4.2,4.1 on Red Hat Linux with
XFree3.3.3. Starting x0 monitor within 8 bit X windows
and using d.mon start=x0 we've got the following errors:

Graphics driver [x0] started
Color: can't set color 0
Color: can't set color 0

Using X windows with 16 bit or 32 bit colour depths we've got:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  78 (X_CreateColormap)
  Serial number of failed request:  270
  Current serial number in output stream:  271

Do any of you have ideas how to fix it?

We appreciate any help.

With best regards,

Jaro Hofierka
