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???

Emne: Re: [Hybrid-graphics-linux] Asus 1215N success 

Right. 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.
