Confirming the issue for gnome-power-manager: it sets brightness level to 100
as soon as it starts.
There is still something else that does the same while ubuntu is loading but
still I don't know which package.
pi...@tux:~$ killall gnome-power-manager
pi...@tux:~$ cat /proc/acpi/video/VGA/LCD/brightness
levels: 20 28 36 44 52 60 68 76 84 93 100
current: 20
pi...@tux:~$ gnome-power-manager --verbose --no-daemon --immediate-exit >
gpm.log
pi...@tux:~$ cat /proc/acpi/video/VGA/LCD/brightness
levels: 20 28 36 44 52 60 68 76 84 93 100
current: 100

** Description changed:
After upgrading to Jaunty brightness settings are not remembered anymore when
rebooting or when disconnecting power cable.
During boot process brigthness changes multiple times:
- at BIOS screen brightness gets correctly restored to last used one
- when ubuntu starts loading brightness is increased (to maximum level?)
- when gnome-power-manager starts it is set to maximum no matter what level
it was set last time and doesn't even care if the laptop is on battery or on
power cable.
