X windows configuration on video card Matrox G400

Hi, I am using RH7.1 linux.
The video card is Matrox G400.
By some reason, I need it to support 1280x1024 with 8 bit color(256 color).
However, I found that I can only configure it as
1280x1024 with 24 bit color.
If I change the color depth from 24 to 8, the X windows can
not start.

Since I need to use one application software in RedHat7.1, I can not use RH7.3 or higher version.

Doese upgrading XFree86 help to this problem?
Is it possible to upgrade the XFree86 to higer version without the major change to other components in RH7.1.
If yes, how to do it? I always got dependence conflict when trying upgrade XFree86 only.

check out /var/log/XFree86.log and see what it says after you change the color depth and try to startx. I can't think of any reason why it would act that way, but then again, I really don't know much about hardware period.

You can definitly upgrade your XFree86 if it comes down to that. The way I do it is by compiling from the sources.... I would recomend that over using a RPM. XFree86 only depends on freetype, so I don't think that you should get that many dependancies. and YES, changing your X server shouldn't mess with anything else.

here's a link to the LFS docs on how to install XFree86.... It should work for you too (you should edit that hosts.def file to fit your system.... or just don't use it at all)

good luck
