We've had years to do better and carried this patch
in both Fedora and RHEL for years and nothing better
materialized, I think we're really doing (other)
downstream users a dis-service by keeping this patch
out of upstream. I can only hope that other distros
are including it themselves, otherwise a lot of
the effort spend on making prime setups work smoothly
is wasted, unless users can find the right magic
xrandr commands to make things work in google ...
