LCD monitor trouble
 
I am trying to get Fedora Core 3 working with my LCD monitor, a Tandberg Ergoscan 15inch. I native resolution of the display is 1024x768, but when X starts my monitor loses the signal and goes into standby mode. I have a TNT RIVA 2 graphics card installed. I have previuosly had SUSE 9.1 installed and working successfully with KDE. I have posted the relevant sections from the Xorg.conf below:


Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unknown monitor"
HorizSync 25 - 40
VertRefresh 47 - 75
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "nv"
VendorName "Videocard vendor"
BoardName "RIVA TNT2"
EndSection

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



Can anyone help me this is driving me nuts?

Thanks

Alan

Your refresh frequency is too high, your monitor is not well configured. Try to detect your monitor by
Code:

Xorg -configure
I have an LCD screen too and this is my xorg.conf parameters. Compare with yours

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "4312 FA"
DisplaySize 340 270
HorizSync 31.0 - 80.0
VertRefresh 56.0 - 75.0
Option "dpms"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection

Thanks for the information. I tried what you suggested ( I changed my refresh rates to match the ones in your file) but it made no difference I also tried adding the DisplaySize field with values of 351 229 which I beleive corresponds to a resolution of 1024x768, this made no difference either.

Any other suggestions?

I have a copy of the working XFree86Config from when I had SuSE installed. Is there any way I can use this to work out what is wrong with my Xorg.conf settings?

Thanks

I would have thought that your working xorg.conf should be OK, as long as all the other hardware remains the same. But have you compared the relevant sections of your working xorg.conf and your current one? I know that it sounds obvious, but a quick line by line check might reveal something. IF they are both the same then changing them will make no difference - IF they are not then you may have found the problem! Jan

Your XFree86.conf file should work (from suse 8, Debian 3, Mandrake 8, Redhat 8), backup your orinal file and use your file from Suse
Good luck.

Thanks guys, I tried copying my XFree68 SusE file to /etc/X11/xorg.conf but the Xserver just crashes with an error "no screens found".
