%description
This driver drives the smartdimmer register found on modern mobile
nVidia graphics adapters such as NV40, NV41, NV43, NV44, NV46, NV47,
NV49, NV4B, C51, G84, G86, G92, G94, G96, GT200 architectures to
adjust the display backlight.

On Apple machines this driver allows more fine-grained brightness
adjustment than the (mbp_nvidia_bl) driver and is generally preferred.

This package contains a DKMS-ready driver for nvidia laptop display
back-lights.

On Apple machines this driver allows more fine-grained brightness
adjustment than the mbp-nvidia-bl-dkms (mbp_nvidia_bl) driver and is
generally preferred.
