xorg changes display brightness

I have a Samsung N150 Netbook.

In /etc/rc.local i put a command to adjust the display brightness to my needs.
Right before the the start of X i can see the brightness flashing up a bit (that's
what i want). But when X is started, the brightness is set back to a lower value.

What is going on here? How can i prevent this?

Probably a (Gnome/Xfce/...) power manager issue. I don't know why they change the brightness but find it very annoying and pointless.

My display manager is SLiM and my window manager is xmonad.
They supposed to be light, right? I just doubt, that it comes from
one of them. However, i do have some laptop-tools /-utilities /
whatever packages installed.

I've added
sudo /usr/local/sbin/backlight set 90
to
./config/openbox/autostart
working fine after login
