Nvidia Optimus GPU on Ubuntu - Via Bumblebee

When the leader of the Autobots is in trouble the underdog Bumblebee is here to help. Now wait, this isn't the plot for the new Transformers movie, go to IMDB for that :) What i am talking about is how to use the GPU switching capabaility aka OPTIMUS bundled with NVDIA Gcards, especially with those superb Dell XPS's.

What little Bumblebee does is it allows you to switch between the on-board Intel graphics solution, ideal for web, docs and stuff, and the multimedia intensive NVDIA powerhouse, in your laptop. It can even allow for simultaneous functioning of both the cards, with each card working on a separate thread(i dont know any scenario i can think of to apply that).

Grab i mean contact Bumblebee at github.com/MrMEEE/bumblebee

Now you can milk more battery life from those monstrously powerful laptops you have :)
