libgl1-mesa-dri-dbg 10.0.0-1ubuntu2 (i386 binary) in ubuntu trusty

 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 rendering.
 .
 For a complete description of Mesa, please look at the
 libgl1-mesa-glx package.
 .
 This package contains debugging symbols for the DRI modules.
