libgl1-mesa-glx-dbg 11.0.8-1ubuntu1 (armhf binary) in ubuntu xenial

 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 modules themselves: these can be found
 in the libgl1-mesa-dri package.
 .
 For a complete description of Mesa, please look at the
 libgl1-mesa-glx package.
 .
 This package contains debugging symbols for the GL library with GLX and DRI
 capabilities.
