I installed fedora 3.0 with a dell M770 monitor and Cirrus logic GD543 video card. The problem is that I can only display 256 colors without getting fuzziness on the right side of the screen. This makes use of the writer and excell type programs problematic as I get some very very difficult to read colors or patterns in the command areas.

I need to either improve the color settings on the display or change the color setting within the other programs to be readable or preferably both.

please tell me where to go.. Also it took a while to load Fedora 3.0 as the config setting for the dell monitor were difficult to find that worked. It is possible that the monitor setting in CMOS are the problem but I have no idea what they should be.

The file you'll want to edit is /etc/X11/xorg.conf (or possibley XF86Config)
Open it as root in a text editor and look for this secton....

Section "Monitor"
Identifier "Dell 2405FPW"
DisplaySize 520 330
ModelName "Dell 2405FPW"
Option "DPMS" "1"
VendorName "Dell"
HorizSync 30-81
VertRefresh 56-76
EndSection


That's what I use, but change your Horiz and Vert refresh rates as per the spec sheet.
Also take a look here:

Section "Screen"
Identifier "Screen 1"

DefaultDepth 24

Subsection "Display"
Depth 8

You'll want to make sure you have 16bit color enabled as well.....
