I would like to try the code out on my Alienware m11x r2.. David talks about mux's and tables... How do I check if my laptop has those???

In that case the closest you can try if you are willing is David Airlie's experimental code here: git repo: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-testing.git branch: drm-nvidia-switch This is not easy to just run, although we've had people giving it a try and commenting on the blog post: http://airlied.livejournal.com/74176.html As it is mentioned in the blog post, there is a debugging mode "drm.debug=0x4" which provides useful information to track down how the MUXes work in each specific laptop model. Other than that, it's a matter of waiting for more info to crop up, there are a handful of users running Linux on 1215n laptops, Cheers.
