I asked the following question at https://answers.launchpad.net/ubuntu/+question/186752 and they told me to submit my question here instead.

I have a Dell XPS 15z laptop with Ubuntu 11.10 and would like to be able to use an external monitor via HDMI. I understand that Optimus is the reason why it doesn't work.

Until there is a better solution I would be happy if I could use only the external monitor and not the laptop screen. According to https://wiki.ubuntu.com/HardwareSupport/Machines/Laptops/Dell/XPS/15z this is possible:

"The HDMI is physically connected to the nVidia card -- by manually changing the xorg.conf, it is possible to start X on the nVidia card only, getting the HDMI video (at the cost of inactive main laptop screen and the Mini Displayport output). "

What should I add in my xorg.conf file in /etc/X11/ in order to use the external monitor via HDMI?
