backlight

I have A Sony VAIO laptop F-series () Nvidia and it has light sensor. When I was using Windows, this light sensor controlled the brightness and the keyboard backlight automatically due to the surroundings state.

But when using Ubuntu 12.04, it only controls the backlight without automatically adjusting the brightness.

How can I enable light sensor to automatically adjustment the LCD brightness without losing the keyboard backlight adjustment due to surrounding state?
