I have a MacBook Pro 5.1 with Karmic. In my /etc/modules I have the nvidia_bl that I think is used to control backlight. But even if I remove the nvidia_bl from /etc/modules I can control the backlight using fn+f1/f2 and it works more gradually and more close to the gauge.
My questions are:
1. nvidia_bl, what is it? I googled around and I didn't find an satisfactory explanation.
2. Should I still use it with Karmic and my Mac 5.1 ?
I've upgraded from Jaunty to Karmic; if you see something wrong, please tell me:
# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
