Bug Description

Binary package hint: gnome-power-manager

here is picture of what happens:
1) I set brightness to 0 level:
levels: 0 1 2 3 4 5 6 7 8
current: 0

2) I press brightness up once:
levels: 0 1 2 3 4 5 6 7 8
current: 2

3) ... once more:
levels: 0 1 2 3 4 5 6 7 8
current: 4

4) ... and once more:
levels: 0 1 2 3 4 5 6 7 8
current: 6

and same for brightness down.
Now I do killall gnome-power-manager, and then repeat test:
1) from 0 level, brightness up once:
levels: 0 1 2 3 4 5 6 7 8
current: 1

2) ... once more:
levels: 0 1 2 3 4 5 6 7 8
current: 2

3) ... and once more:
levels: 0 1 2 3 4 5 6 7 8
current: 3

This is correct behavior, when g-p-m is not running.

gnome-power-manager --debug --verbose --no-daemon produces no output, so no logs to attach
