I can’t recall if I already posted this, but I did manage to get the VGA output working in order to use a external monitor or projector for my Dell 700m on Ubuntu. For this laptop the Fn-F8 key doesn’t work for whatever reason. Probably some BIOS or motherboard firmware problem that requires a driver in windows. Anyways, trying to use i810switch or i855crt both produce horrible results. Therefore, the only way to get this to work is to enable a dual head configuration.
In order to do this, just add these two Option lines to your xorg.conf file:
Section "Monitor" Identifier "Generic Monitor" Option "DPMS" HorizSync 28-64 VertRefresh 43-60 Option "MonitorLayout" "CRT,LFP" Option "Clone" "true" EndSection
Found this great page after much searching and most of the configurations work well.
