Fix your laptops brightness function keys operating properly in Hardy
Before doing any changes you need to take backup of existing files
Now you need to download the following files in /etc/acpi/ directory
Download video_brightnessup.sh from here
Download video_brightnessdown.sh from here
After replacing these scripts
No reboot or logout required, simply press your function combination on your laptop to change brightness. Try to press FN + Up/Down Arrow.

i am using sony vaio vpccw13eg.I installed linux mint 9 but i am unable to adjust screen brightness. i tried above written tips. Its not working.So please suggest me something.
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:
Identifier “Default Device”
#Next line is essential to have a working brightness function
Option “RegistryDwords” “EnableBrightnessControl=1”
It is gr8 and very easy solution. It works fine for me for my laptop HP Compaq nx6110 (Ubuntu 11.04).
Login with root user and copy both the files at /etc/acpi/ folder.. thats all.
Thanks a lot.
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.
