Right, that shows it: It first tries the XBACKLIGHT extension:
TI:17:40:53 TH:0x840f168FI:gpm-brightness-xrandr.c
FN:gpm_brightness_xrandr_setup_display,170
- No outputs have backlight property
TI:17:40:53 TH:0x840f168FI:gpm-brightness-xrandr.c
FN:gpm_brightness_xrandr

Here you go...
b...@aao-lin:~$ hal-device /org/freedesktop/Hal/devices/computer_backlight
libhal.c 546 : No device with id /org/freedesktop/Hal/devices/computer_backlight
org.freedesktop.Hal.NoSuchDevice: No device with id

I have attached the full
xev looks correct (there's one event each for key press and key release,
so they appear duplicated). So everything is alright with the hotkeys

So now it seems to be a problem in gnome-power-manager or hal, and their
handling of your particular backlight device. Can you please do
kil
