Sony Vaio iluminated keyboard
I have version 12.04 of Ubuntu, and a problem I do not know how to fix.
I have a Sony Vaio computer with backlit keyboard. On the laptop I have a button that if you press it in Windows there it call a program where you can change the configuration of the laptop, and one of the sections is on or off the backlit keyboard, (I have to do that with a program, the keyboard doesn't have a button to do it directly.).
Well, the problem is that I haven't this program in Ubuntu. When Ubuntu start, the backlit keyboard is on (it lights when I press a key and off after X seconds).
I want to know that there is any way to be turned off and only the backlight turns on when I want. I try to look for in Google, and posted in official Spanish Ubuntu forums, but nobody can help me.
Sorry fot bad english, I am from Spain.
