dimming problem

[Oguz Yarimtepe]

I have been trying to dim my backlight. Till now i couldn't find a 
solution. Thats why i entered a bug report[1].

I decided to ask here also. There may be a problem with gnome power 
manager and gnome brightness applet at ubuntu hardy, or maybe the latest 
nvidia drievers dont support dimming. I dont know.

What i want is some ideas. I tried xbacklight and smartdimmer but as i 
wrote at the bugreport i didnt get any result from them. I can try to 
fix them if it will have a solution. So any one who is using a nvidia 
5600 series graphic card under Hardy may share his/her experince about 
dimming.

What i want is not to adjust the brightness from the nvidia-setting, to 
adjust the voltage of the backlight in some way so i can save power. Any 
ideas are also welcome related with my problem.

And how can i adjust the voltage coming to backlight? Is there any 
library that i can use for that? I may try to write my own program.
