Nvidia optimus is a nice (but complex) idea that consist in integrating an Intel graphic card among a Nvidia graphic card.
Meant to be used for laptops in order to have a good battery saving mode, so that when GPU (graphic card 3D accelerated) is not required, the Intel card is used, and when the user wants more power or just to play games, Nvidia is used. The switch is meant to happen "on the fly"
This should be not hard to integrate in Elive, and it already includes the needed packages by default (like bumblebee), but unfortunately I have no machines to test it, so please somebody try to make it working in Elive and tell me which configurations are needed to have it working "out of the box" by default (instructions steps, write a howto in #howtos). The nvidia installer of Elive already includes some information for the user to make it working.
@Rebel450 is one person that has this type of hardware, so can be a candidate to test it
