I have problem one big problem . Every time I put my laptop (Dell Inpiron) on battery, system reduces my screen brightness (dims my screen).
I was trying to play around with xfce4-power-manger put it's completely useless.
I hade this problem before, but then I could easily fix things with gnome-power-manager (just clicking on brightness tab). The worst thing that gnome-power-manager by itself is not working here on #! unless you have all GNOME GUI installed.
I was wondering maybe somebody knows how to make system not reduce screen brightness than laptop is on battery? Thanks for help.

Could it be in BIOS?
Take a look at this thread: http://crunchbang.org/forums/viewtopic.php?id=11954
The script contains a setting to reduce the screen brightness when on battery, but it could be modified to set the brightness level to anything you want.

Triple booting CrunchBang, Ubuntu and Windows 7
see if setting keybindings for xbacklight to super + up/down to adjust screen brightness works!

are you using a screensever, is there some options to to dim screen on look or something!
# Since you've tried with the other PM tools , try this one :
have you checked if your brightness Fn keys function properly! I mean, do they even work ! what happens if you use them ..
i have a friend with an old toshiba , his multimedia keys got scrambled due to his BIOS manufacture cotnflict and limitation!
so i had to SSH to his Box, and had to check with udev.rules and debug/backtrace and stuff to set keycodes .
just saying ..
