Suse 8.1 fails to detect my monitor

Hello

I installed Suse 8.1 on my pc, however the installation fails to detect my monitor (Dell 15 inch Flat Screen e151fp) and as a result to selects a very big screen resolution 640x480. Not matter what I try I cant seem to change this, I cant do it on Yast, no matter what resolution I select it fails the validation test.

I also tried to modify the XF86Config file but this doesnt seem to make any difference. If I force the pc to use a higher resolution eg 1024x768 it displays a error message during boot up saying that it is unable to display the video mode. This happens even if I insert the correct vertical and horizonal refresh frequencies.

The following is the relevant part of my config file

Tried sax2 ?
Type "level 3" at the boot prompt and start it with Sax2 as root.
If it does not recognize your monitor at all try it with:


Section "Monitor"
Option "CalcAlgorithm" "UseFrameBufferTiming"
HorizSync 31-60
Identifier "Monitor[0]"
Modelname "XGA 1024X768@60HZ"
Option "DPMS"
VendorName "--> LCD"
VertRefresh 60-75
UseModes "Modes[0]"
EndSection

no guarantee, sorry

Im afraid I tried that and it didnt work, any other suggestions
