I am dual booting. Win7 for the occasional game, and Ubuntu 12.10 for everything else.
I've got a Nvidia 680m 4GB GPU. At https://wiki.ubuntu.com/Bumblebee
If I only want to install bumblebee for its power savings feature. Is it enough just to run:
`sudo apt-get install --no-install-recommends bumblebee linux-headers-generic`
Or should I install the proprietary drivers from Nvidia, via:
`sudo apt-get install bumblebee bumblebee-nvidia linux-headers-generic`.
Is there any difference for power saving between the two drivers?
