How to turn the keyboard back-light off for sony-vaio laptop. I have tried most of the methods described on the forum but to no avail.

My laptop is sony-vaio SVE15117FNB. And I am using Ubuntu 14.04.2 LTS Trusty.

  • The commands are xset led 3 to turn the backlight on and xset -led 3 to turn the backlight off. – Terrance Apr 21 '16 at 22:26

Open terminal and try this:

xset led off

If that doesn't work get this.
