Comment 30 for bug 80940

I have the same laptop model and both Ubuntu Intrepid Ibex and Jaunty can't detect my maximum resolution of the laptop screen which is 1400x1050. The only modes i have to choose from are - 640x480,800x600 and 1024x768 and the funny thing is that on older versions of
Ubuntu (Feisty Fawn and Hardy) I could fix it by changing xorg.conf to:

//////////////////////////////////////////////////////////////////////////////////////////////

I now use Ubuntu Jaunty and i tried changing my xorg.conf to:

///////////////////////////////////////////////////////////////////

Section "Device"
 Identifier "Configured Video Device"
        Option "IgnoreEDID"
EndSection

Section "Monitor"
 Identifier "Configured Monitor"
 DisplaySize 286 214

 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"

SubSection "Display"
 Modes "1400x1050"
EndSubSection

EndSection

and it doesn't helps me either.

This is my xrandr command output :
