Don't look only at the vendor string - that is the OpenGL library
shared library indication only. You would see Mesa there only if you
switch the libGL.so to point the libMesaGL implementation.

You need to check whether the "Direct Rendering: Yes" is present in
the output - that is what indicates that the GLX module is actually
working.
