Seems I needed to adjust the correction_factor gconf key in gnome-power-
manager - in good light, the light sensor would be

cat /sys/devices/platform/applesmc.768/light 
(4,0)

and then covering it with my hand, I'd get

cat /sys/devices/platform/applesmc.768/light
(0,0)

So it seems to be reading quite low, changing correction_factor to 10000 seems to give some appropriate results... I am a little concerned about the 0 reading from the right sensor though - is this something specific to the applesmc driver on MBP 5,1 or is it more indicative of some hardware
fault??

i am using a macbook pro 3.1 with intrepid beta and the nvidia driver. i finally managed to have the backlight keys F1 and F2 working but now i face another problem. when i change the backlight setting, it resets itself after some minutes to an average light level. then i use f2 to increase backlight again and some time later it goes down again.i have deactivated the shade setting in the gnome power management. the light is also turned down while moving the mouse or typing.
