Switcheroo is what you're looking for, vga_switcheroo is the kernel mechanism that allows you to switch between GPUs (if you have Hybrid graphic system). Since linux 3.3, this is working again with NVIDIA Optimus (fix: http://git.kernel.org/cgit/linux/kernel/git/next/linux-next-history.git/commit/?id=d099230cc355c485e556121c034b1fca5a5fd18b),
Here you can find everything you need to know about this feature: https://help.ubuntu.com/community/HybridGraphics
Anyway, for NVIDIA Optimus, you can also use Bumblebee: https://wiki.ubuntu.com/Bumblebee
