Brighness level adjustment weird behavior

Bug Description

Binary package hint: gnome-power-manager

On my Toshiba Satellite U-300, Fn keys and Gnome power management tools (including Gnome-Panel's brigthness applet) seem to work independently.

I can adjust the brigthness using the FN keys, and it won't affect the applet slider, for example...

Sometime, in the middle of a session, they seem to synchonize randomly, affecting the screen brightness.

Also, the setting in gnome-power-management (using gconf-editor) don't apply correctly.

I confirm I have the same problem:
- Fn keys do change the brightness and a OSD with the new brightness is correctly displayed, but the slider in the gnome applet does not update accordingly

Moreover g-p-m ignores the gconf settings /apps/gnome-power-manager/backlight

My backlight settings are:
$ gconftool -a /apps/gnome-power-manager/backlight
 idle_dim_battery = true
 idle_brightness = 30
 dpms_method_battery = default
 dpms_method_ac = default
 idle_dim_time = 10
 brightness_battery = 10
 enable = true
 idle_dim_ac = true
 brightness_ac = 90
 battery_reduce = true

but this happens if I unplug and re-plug the AC:
signal sender=:1.14 -> dest=(null destination) path=/org/freedesktop/PowerManagement/Backlight; interface=org.freedesktop.PowerManagement.Backlight; member=BrightnessChanged
   uint32 20
signal sender=:1.14 -> dest=(null destination) path=/org/freedesktop/PowerManagement/Backlight; interface=org.freedesktop.PowerManagement.Backlight; member=BrightnessChanged
   uint32 100

It should have been 10 and 90, rather than 20 and 100.
