I thought that the AMD GPU would kick in automatically when needed. From AMD, "Switchable Graphics technology engages discrete graphics only when it is needed for 3D applications, and uses energy-efficient integrated graphics capabilities the rest of the time.". Read this.
The Intel GPU is always primary - the AMD GPU is just a co-processor. All video data passes through the Intel GPU on its way to the screen -- there is no physical connection between the AMD GPU and the screen. It is not and cannot be made the primary GPU in the system.

ejn63,
Thanks for the clarification. Makes me wonder why AMD didn't develop something like Nvidia Optimus?
