Public bug reported:
Starting with Mesa 21.2 an alternative driver for Intel hardware for
Gen4 through Gen7 is available that is based on Gallium3D.
It provides new features (like the Gallium Nine state tracker) and
improved performance in some scenarios. Since the driver is still
experimental, it is no enabled by default but can be selected by setting
the
MESA_LOADER_DRIVER_OVERRIDE=crocus
environment variable.
Ubuntu does not enable the driver in it's mesa build, when selected I
will just get this error message instead:
$ MESA_LOADER_DRIVER_OVERRIDE=crocus glxinfo
libGL error: MESA-LOADER: failed to open crocus: /usr/lib/dri/crocus_dri.so:

/usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
