Welcome to our wiki!
Many recent notebooks with a discrete nVidia card in it and an i3/i5/i7 processor use the nVidia Optimus technology to improve battery life. Unfortunately, this software solution is only available in Windows 7 and later.
The Bumblebee Project is a set of tools developed by people aiming to provide Optimus support under Linux (legacy nVidia hybrid graphics is supported too) while waiting for kernel and drivers to support these notebooks.
