This is technically impossible to do, because the kernel only allows one driver to drive a piece of hardware. Even if we rearchitected the kernel to allow multiple drivers in a co-operative manner, it still wouldn't be possible unless the proprietary drivers were modified to do this hand-off. The only way to achieve what you are suggesting is to unload a FOSS driver and load a proprietary driver when you started e.g. Steam. Then do the opposite when you exit the game. That is basically a tear-down of everything and you might as well reboot. The idea is nice, but it isn't feasible at all. We have a better chance of just making the FOSS drivers as performant as the proprietary drivers. At least that is somewhat realistic. josh -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
