Hi all, Here is a patch series to make video.use_native_backlight work on laptops with nv gfx, at least on those were nv gfx have a raw backlight interface.
I've tried this on my own somewhat old nv equipped laptop, but that does not have a raw backlight interface. I'm currently doing a scratch build of the Fedora-20 kernel with this patches for the user with an affected system to test. Regards, Hans
