lightdm, xfce4 and backlight

Hi, I'm having one problem...blackscreen after login, I can use my hardware keys to bright up, but I'm wondering something automatic and persistent, I don't have blackscreen from boot to lightdm screen login. After login I have the blackscreen

/usr/bin/dimup:

#!/bin/bash

# xbacklight -inc 40
setpci -s 00:02.0 F4.B=40

Now, I added also in all my /sys/class/backlight/*/brightness files the "echo 5"...nothing.
In my $HOME/.xinitrc also added setpci and xbacklight...with no luck.
Even added an entry in xfce session manager the /usr/bin/dimup to execute after xfce, same bad luck..

so, any ideas??

Do you can 'echo 5 > /sys/.../brightness' manually? Maybe it's privileges issue, try to chmod (worked for me when i couldn't set brightness)

May try to search how XFCE does it, on my laptop the backlight settings are restored by KDE itself.

@severus: Might can, but..I'll be blind work :-/
@Thaodan: I'll ask on their forums
