dual screen on alienware 13r2

Hey guys,

I've been trying for a while to get dual screen happening with nvidia proprietary drivers on Arch with my alienware 13r2.

To date I've only been able to get it to register either my external monitor via hdmi or the laptop monitor. At the moment I have it working with only the external. Some outputs:

uname -a

so the laptop monitor is not being recognised by xrandr. It also doesn't show up in the nvidia manager. Any suggestions how to gett hem working?
