Are you sure it's using the driver you built instead of the system
installed driver?
LIBGL_DEBUG=verbose glxgears
will give some information about the driver being used (see below). If
that doesn't match the driver installed, you'll need to use
LD_LIBRARY_PATH and possibly LIBGL_DRIVERS_PATH to get the right one.
libGL: OpenDriver: trying /usr/lib64/dri/tls/i965_dri.so
libGL: OpenDriver: trying /usr/lib64/dri/i965_dri.so
libGL: Can't open configuration file /home/idr/.drirc: No such file or
directory.
