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.

This is a continuation of the problem adressed with upstream commit 551461841d64f6f 1cdea6a92e, to this problem: https:/ /bugs.launchpad .net/ubuntu/ +source/ hal/+bug/ 226894

It is correct that MacBookPro3,1 and later are not listed to use the macbookpro addon. However, the light_sensor and keyboard_backlight devices are also driven by the same addon, and thus the newer macbooks should not be listed there either.
Assuming that the gnome-power-manager still treats the listed but missing light sensor, the symptom described in this bug makes sense.
The suggested fix is to remove MacBookPro3, 1;MacBookPro3, 2;MacBookPro4, 1 completely from fdi/policy/ 10osvendor/ 10-macbookpro- utils.fdi, and instead implement keyboard_backlight and light_sensor through the mechanism outlined in https:/ /bugs.launchpad .net/ubuntu/ +source/ linux-source- 2.6.22/ +bug/125918.
