Well, in a way it is. If I'm not mistaken, most Optimus devices have their video outputs directly connected to the Intel GPU so it's just a matter of disabling the NVidia one. On at least some Macbook models, the video output are connected to a third chip, and this chip must also be told to talk exclusively to the Intel GPU at boot time first. -- Francois Tigeot
