NVIDIA Optimus
This page describes how to identify, configure and troubleshoot NVIDIA Optimus enabled systems for Debian. NVIDIA Optimus is a technology that enables dynamic, switchable graphics between the central processing unit's (CPU) embedded graphics capability and the discrete graphics processing unit (GPU) card. Due to the nature of this technology, various software components must be aware of, and configured for, the proper output of the display based on the user's desired configuration.
The instructions on this page apply to Debian Wheezy and newer.

Installation of Proprietary Graphics Driver Required
The instructions on this page assume that your system has already had the NVIDIA proprietary graphics drivers installed using the instructions, here: ?Driver Installation.
Identification
The quickest method to determine if your device uses an Optimus card is to search against the documented list on NVIDIA's website. Obtain the NVIDIA GPU identifier of your card with:
$ lspci | grep 3D
Compare the identifier (i.e. GeForce 7XXM, 8XXM, 9XXM) with the list, here: http://www.geforce.com/hardware/technology/optimus/supported-gpus
Also note the PCI identifier of the card, which is the 5-digit ID at the beginning of the previous command's output, XX:XX.X.
