Hi,
Thanks a lot to all of you who answered for your quick response time (I
needed it)
Spaciel thanks to Chris Vandersip who has given me a detailed
explanation of how to solve my problem. I have followed his instructions
and it works fine.
This is his answer:
> 1. First run "xdpyinfo > xdpyinfo.out". This will list, among other
> things, the "default visual id" for the system. Further down the
> list
> you'll see a description of all possible visual id defaults. Our
> default was "0x22", which corresponds to TrueColor, 24-plane mode.
>
> 2. This default is established in the "Xservers" file, located in
> /usr/lib/X11/xdm directory. Within this file is the command to launch
>
> the Xserver, given by: ":0 local /usr/bin/X11/X", which should be a
> link to /usr/bin/X11/Xdec. The "-vclass" option for Xdec allows one

> 3. To change the default to 8-bit PseudoColor, append that Xserver
> launch command with the following:
>
> -vclass0 PseudoColor

> Note: On our system the Xserver file was initially read-only,

>
> 4. Shutdown and reboot the system. Logon and execute "xdpyinfo"
> again
> and your new default visual id should be PseudoColor, 8-plane mode.
> Our

> visuals, just the default will be 8-bit.
