w530 在ubuntu 12.04 _x64 背光调节方法

So to get the screen brightness keys working with your Nvidia graphics card, create a file in the xorg.conf.d directory, e.g:

sudo gedit /usr/share/X11/xorg.conf.d/10-nvidia-brightness.conf 

Paste the following into the file:

Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro K1000M" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection 

Log out and log back in, or reboot, and your brightness keys should now work!
