How to make GNOME remember brightness setting

For the sake of long battery life I decrease my laptop's brightness as soon as I log in but when I reboot the laptop. The Brightness goes back to full and I have to decrease it again. Its really bugging me now.

Is there a way to permanently set the brightness level.

You could try acpitool. It might not work on your laptop, but its worth a shot.

for minimum brightness:

acpitool -l 0   

for maximum brightness:

acpitool -l 7

Now you just need to add that command to your startup script.

note: the above command must be run as root.

My apologies, I should have looked into it more. I found the option of configuring brightness in Ubuntu tweak.

the option to control the brightness can be found in 'power Management settings' under the tab system on Ubuntu tweak

I know that, I changed the title so that no one else bother about answering it. I cant accept my own 'answer' as accepted before 2 days. I think this is good enough reason to satisfy the reason of changing my header. – Gaurav Butola Oct 29 '10 at 10:00
@Guarav No need to apologize, remember someone will run into this too, please link to what Ubuntu Tweak is so the next person can benefit! – Jorge Castro Oct 29 '10 at 12:45
