Optimus is actually for switching between two different graphics
chips on the fly (a lower-power/performance once when you're not
doing heavy 3D, and a power-sucking performance daemon when it's
time to play games).   If the lower-power one is the Intel integrated
graphics in a Sandy Bridge or similar chipset, then it's not surprising
the nvidia driver doesn't work when you disable it.
