i have two monitors. one on an x1250 (rv410) IGP, which is only supported by legacy catalyst or the free drivers, and the other on a hd2600pro (rv630) card, which needs catalyst to be usable (mostly because of power management).
What are my options to use them both?

do i have to use catalyst 9.3 like with windows? would 9.3 even work with modern distros?
