So, after investigating this problem, I finally saw the cause: under
X.org, the environment variable LIBGL_ALWAYS_SOFTWARE is set to 1
*always*. Without it, it uses the intel driver as usual:
$ LIBGL_ALWAYS_SOFTWARE=0 glxinfo | grep -i opengl
OpenGL vendor string: Intel Open Source Technology
Ok. Is there any other command to run or logs that I can add to spot the
problem of it using llvmpipe?
