libgl1-mesa-dri-experimental 7.10.3-0ubuntu2 (i386 binary) in ubuntu oneiric

 This version of Mesa provides GLX and DRI capabilities: it is capable of
 both direct and indirect rendering. For direct rendering, it can use DRI
 modules from the libgl1-mesa-dri package to accelerate drawing.
 .
 This package does not include the OpenGL library itself, only the DRI
 modules for accelerating direct and indirect rendering. The drivers
 in this package may provide more features than the drivers in the
 libgl1-mesa-dri at the cost of less stability.
 .
 For a complete description of Mesa, please look at the
 libgl1-mesa-swx11 package.
