libgl1-mesa-dri 6.3.2-0ubuntu6 (i386 binary) in ubuntu breezy

A free implementation of the OpenGL API -- DRI runtime
 This version of Mesa provides hardware-accelerated rendering
 capabilities for cards supported by the DRI project, which
 provides accelerated direct rendering (bypassing the X server). This
 package provides the userspace DRI modules; a server which supports
 the XFree86-DRI extension, and a kernel DRM module for your card, is
 still necessary to use accelerated direct rendering.
 .
 For a complete description of Mesa, please look at the libgl1-mesa package.
