Comment 6 for bug 1378418

Will do, but i guess not before the weekend. Tonight i've did some easy debugging by just installing some old version (3.14-3.16) of the mainline kernel. It showed, that the actual bug (not being able to adjust the brightness level after undocking) is fixed in those versions as well, but there is some other strange stuff going on. After every undocking the screen is just black. I first thought the OS/windows manger/... crashed, but after some testing it showed, that the brightness level was just set to the lowest possible value which just meant that the display is black/dark. So with 3.14-3.16 the actual bug is fixed but there is some really non-user-friendly behavior with just a black/dark screen.
So i guess i should first bisect 3.13 against 3.14 to find the actual bug(fix)? And after that bisect 3.14 against 3.17 to find the bugfix for the black/dark screen behavior. Right?
