Default Re: Backlight gets reseted with VDPAU

I guess this problem isn't surprising then; the nvidia kernel driver owns all GPU registers and has no provisions to share them. Hence, any changes made by nvidiabl can and will get over-written. I'd imagine this is happening with VDPAU in particular, because it programs various display registers to set up the overlay.

Why is nvidiabl needed; are there bugs in the nvidia driver that should be addressed instead?
