optimus

I have a Dell Latitude E6420 laptop with Ubuntu 12.04 alongside Windows 7 (dual-boot) docked in a docking station with 2 DVI outputs.

It took me a week of tinkering to get the dual external monitors to work in Ubuntu, and I had to disabled the "Optimus" feature in the BIOS. But now neither external monitor is detected in Windows, and the resolution is also very low.

Do you know how I can successfully dual-boot Windows 7 and Ubuntu on this machine using my 2 external DVI monitors?

I have an open question here too, trying to resolve this same issue: http://askubuntu.com/questions/146933/dock-with-dual-external-dvi-monitors-with-intel-nvidia-optimus
