Fedora 8 LCD Monitor Problem


Hello Recently I have purchased fedora 8 CD. before that I was using Fedora 6. with same monitor and same hardward. I can able to see all colors on the monitor. but As soon as I am started installing on Fedora 8 on LCD based Monitor. some colors are missing ( even more specific they are light gray color) I thought after installation it will work. and even after installation it didn't shown it properly. I have LCD LG 1520B monitor. I have total 4 machines out which 2 runs on windows and 2 runs on linux. out of both linux one having CRT LG monitor and other having LCD 1520B monitor.

where CRT based monitor works perfectly and all colors are pleasant. but in LCD it didn't shown properly. so I changed another monitor of windows machine. thinking that that might be a hardware problem. but same monitor working perfectly on windows machine. giving same result on Linux (i.e. gray color missing) so its not hardware problem.

Finally Tried to change the resolution and frequencies doesn't help me. after a long search on google I find LG1520B's max frequency and added this code in xorg.conf
Code:
Section "Monitor"
	Identifier   "Monitor0"
	ModelName    "LCD Panel 1024x768"
	HorizSync    31.5 - 63.0
	VertRefresh  56.0 - 75.0
	Option	    "dpms"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "radeon"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Viewport   0 0
		Depth     16
		Modes "1024x768" "800x600" "640x480"
	EndSubSection

EndSection
if any one their , who can help me what will be the problem? what setting is needed so that I can able to see the proper color with LCD monitor+ Fedora.

colors are handles through depth. please go into your yum program and let it do it for you. because if you never used the xorgconfig you could do some bad things like no xwindows ok.
you might be surprised it might actually have your monitor type listed to. good luck

Generally speaking yum does not handle xorg problems.

Backup you xorg.conf, change the "Depth 16" to "Depth 24", save changes, logo out, log back in, and it SHOULD be cleared up. If it is not cleared up you probably have a driver issue and that (since it is a raedon) is a more complex issue.

Yes, but if you look further down you will see "Depth 16" is listed. Generally xorg only remembers the last setting it gets.
