Nouveau: Accelerated Open Source driver for nVidia cards
The nouveau project aims to build high-quality, free/libre software drivers for nVidia cards. “Nouveau” [nuvo] is the French word for “new”. Nouveau is composed of a Linux kernel KMS driver (nouveau), Gallium3D drivers in Mesa, and the Xorg DDX (xf86-video-nouveau).
2D/3D acceleration supported on all cards; see FeatureMatrix for details
Experimental support for performance level selection (also known as "reclocking") on Kepler and GT21x GPUs. Boot with nouveau.pstate=1 to enable. Expect low 3D performance Fermi GPUs.
