How can I enable vgaswitcheroo in Fedora 18??? TO be honest with you all, this is the only thing that has kept me away from fedora and sticking with Ubuntu. I cannot find any tutorials or post that explains how to enable vgaswitcheroo in neither fedora 17 nor 18.

Im new to linux scripts.

I am running the new Ubuntu 12.04 64-bit release on my MSI CX420 laptop.
