Just installed Ubuntu 14.04 on my laptop and have been searching the internet for a couple of hours, trying to get my keyboard's backlight to work . I know it works out of the box when you hit the little icon on the laptop, but the only color it's able to show is bright white and I want it to show multiple colors just like on windows.
I have made a little guide for myself for future reference and I felt like posting it here to help other people with the same laptop/keyboard.
Have fun,
