It's possible the OP meant installing the drivers for his laptop's hybrid graphics setup, which would include Bumblebee.
If that's the case, there have been other threads here concerning that. You can check out these two for starters, here and here.
I'm assuming your particular laptop is one that came with the Nvidia chip, according to this thread, not all of them did. _________________ Our Lord and Savior Jesus Christ loves and cares about you most of all!
