install compizconfig setting manager,
from compizconfig--opacity and brightness--brightness tab you can enable your brightness function. its working for me.
you need to give shortcut you want to use.

@John:

I am using Linux Mint too (version 11) and the same problem here. To resolve the problem try the following.

You will need to add this to your xorg.conf:

Section “Device”
Identifier “Default Device”
#Next line is essential to have a working brightness function
Option “RegistryDwords” “EnableBrightnessControl=1″
Driver “nvidia”
EndSection

I have tried with new kernel installation. The Display of brightness control is coming when I am pressing keyboard button and the applet is also showing up down controls. But the brightness is constant.

Thanks for any update.

Iff you are using Gnome, right-click on the panel you want to add it to, select “Add to Panel”, then drag the Brightness Applet to where you want it on the panel.

hai..im using acer aspire 4736 laptop.
im also having the same problem as you guys.
My diplay brightness is not functioning.

My solution is:
---------------
1. Install COmpiz (Advanced Desktop Effect Settings (ccsm) from Add/Remove..

2. After finished, go to System > Preferences > CompizConfig Settings Manager.

3. At Accessibility Column, tick the Opacity, Brightness And Saturation and click at the word.

4. There are Opacity| Brightness | Saturation tab. Choose the brightness tab.

5. You will see keyboard(increase),mouse(increase),keyboard(decrease),mouse(decrease) icon at the left. At the right of it, you will see Disable button.

-Brightness Increase-

6. Click at the disable button of keyboard(increase) and tick the enable box.

7. Now, put your own combination. Lets say we want to make it as CTRL + right button. There are a choice:

Shift Super
Ctrl Alt

8. Click at the Grab key combination.

9. ccsm windows will pop up. Press ctrl + right button on your keyboard and press ok..

10. Now you have done for the Brightness increase button.

-Brightness Decrease-

11. Click at the disable button of keyboard(decrease) and tick the enable box.

12. Now, put your own combination. Lets say we want to make it as CTRL + left button. There are a choice:

Shift Super
Ctrl Alt

13. Click at the Grab key combination.

14. ccsm windows will pop up. Press ctrl + left button on your keyboard and press ok..

15. Now you have done for the Brightness decrease button.

-Try it OUT-

Now, go to the desktop and press CTRL + left button on your keyboard repeatedly and CTRL + right repeatedly.

It is working??

Note: this brightness working at all active windows.

try open up mozilla and press the CTRL + left button. Mozilla will get dimmer.
Try open up terminal and do the same things. The terminal will get dimmer to.
press CTRL + right to get it brighter.

Happy playing!!!

Have you tried the brightness applet on the panel too? (You may have to manually add it.) If that doesn’t work, it probably is a driver problem.

I have a Acer Aspire 4736G laptop with Ubuntu 9.10 (Karmic Koala) installed on it. And I have the same problem as cees above. The FN+ combination shows that the brightness is decreased/increased but the screen remains in same brightness. I can change the brightness using the same combination in my Windows. Please suggest a fix for this problem. Is this a problem with not installing Acer drivers or is it a problem with Ubuntu?

Update to my earlier comment on Ubuntu 9.10. Using the beta, the brightness controls were DOA, but when I installed all the updates after the final release, the brightness widget suddenly started working on my Vaio Z530N.
