UL80VT Dual graphics problem

[fyodor.co.cc]

Hi there, it's the first time I post new topic, @mod, if I post wrong section, please move it to right section for me, I will try to post right section next time.

The problem is, I have Asus UL80VT, decide to make 12h battery & dedicated graphic card Lion hackintosh.

My spec :

- Integrated VGA 128MB

- nVidia 210M 512MB

- Intel Wifi

...

 

When install with retail DVD, it works with Camera, Sound (VoodooHDA), keyboard (VoodooPS2), 1366x768 (but using Graphics Enabler = yes, Graphics Mode = 1366x768x32, screen looks blur).

System detects nVidia 210M but I think it is using Integrated VGA instead of nVidia graphic card.

So how to switch between these cards

Thanks !!!
