currently, only support for fully disabling nvidia is provided, which is helpful for saving power/heat. In the future, this should be extended so we can choose: - nvidia only (choose between nouveau/nvidia driver) - IGP only - Hybrid (choose between nouveau/nvidia driver, use the "bumblebee" package/daemon) svn path=/nixos/trunk/; revision=32085
