xserver-xorg-video-nouveau 1:0.0.15+git20100128+2630a15-0ubuntu1 (amd64 binary) in ubuntu lucid

 This driver for the X.Org X server (see xserver-xorg for a further description)
 provides support for NVIDIA Riva, TNT, GeForce, and Quadro cards.
 .
 Note that these drivers are INCOMPLETE, and are only really useful for testing
 at this point. People needing a stable driver should use the "nv" driver
 instead. Although the upstream nouveau drivers provide some 3D support, these
 packages do not include the necessary files. Users requiring 3D support should
 use the non-free "nvidia" driver.
 .
 This package is built from the FreeDesktop.org xf86-video-nouveau driver.
