Solution to Intel 945GM resolution problems in Ubuntu

Problem: I wasn't getting the maximum display resolution while using my LCD monitor over DVI. The only option in Ubuntu 8.10 Screen Resolution was to mirror screens or have dual output because of LVDS on the motherboard.

It looks like LVDS is getting enabled even when it's disabled in the BIOS.

This should work for most Intel 945XX users:

gksudo edit /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "monitor-LVDS" "LVDS"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Monitor"
Identifier "LVDS"
Option "Ignore" "True"
EndSection

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