NVIDIA Quadro 2000M
Linux driver - OpenSource
nouveau is the Open Source driver for nVidia cards. The "most recommended" way to install nouveau is through your distribution-provided packages, though you can install from source. For more details about the project, as well as ongoing development, see the project's website or your distribution's wiki pages.
The Quadro 2000M GPU is based on the Fermi architecture; Linux kernel 3.1 or newer is recommended for optimum support by the nouveau driver.
