Eu instalei recentemente o Ubuntu para inicialização dupla no meu MacBook. No entanto, o recurso de brilho não funciona! Aconteceu somente depois que eu mudei o driver de exibição. Estou usando o Ubuntu 13.04

Estranhamente, o driver da Nvidia que estou usando não está aparecendo como em uso na saída acima. É o NVIDIA binary Xorg driver, kernel module and VDAPU library from nvidia-310
Como corrijo o brilho no computador?
