Bright configuration


Hi, i'm just starting to use Linux. I've been able to solve all my problems so far, but i just couldn't fix this:
I have a problem with the brightness. I use it on minimum, but, i.e. while reading a book, when i don't touch the mouse or keyboard for a while, the bright goes up to half, and then, when I do anything, it goes up all the way. My guess is that it's configured to go down till half since you've been inactive for a while and then go full like it was the original state, instead of returning to minimum.
So, how can i configure it?
BTW I'm using Xfce on Huayra (shitty Argentine-made distribution).

$ xrandr

$ xrandr --output VGA-0 -brightness 0.95 --gamma 1.25:1.25:1.25

for me to watch hulu with excessively black-ish content and see what's going on.

$ xrandr --output VGA-0 -brightness 1 --gamma 1:1:1

to restore the defaults. There's also xcalib and other methods like amdcccle for fglrx / amd / ati driver.

It's probably something with DPMS or cpu frequency scaling in your case.

sounds like laptop screen dimming when running on battery.

check xfce4-power-manager settings.

there's also xgamma for manual adjustments.
