How To Get Sony Vaio Backlight Working Under Linux

Got a Sony Vaio with backlight capabilities?
If you answered yes to that question and it's not working I found a workaround.
Open the terminal as root and create this file in Nano or any other text editor.
Before you close that file put this argument in it:
Than save the file.
(2 is 60 seconds and 3 is unlimited) I recommend setting it to 2.
Than after making that file open the terminal and run this cmd as root:
The keyboard should light up.
I'm working on finding a way to make it permanent. For now each time I boot up the Vaio I have to run that echo cmd each time for the backlight to work.
This worked for Sony Vaio model SVE 151190x Enhanced E Series.
I can't guarantee it will work with all Sony Vaio's but it can't hurt to try.
If it doesn't work it could be that the light is burnt out and needs replaced.
Sadly Sony is not making Vaio's anymore so you'll have to repair it yourself or take your Vaio to your local computer repair shop.
If you have a Micro Center close to home I recommend them.
