Bug Description
Using kernel 3.19.0-66-generic the keyboard backlight and screen-top illuminator work.
However, after upgrading to kernel 4.4 the keyboard backlight and screen-top illuminator come on without hitting the special keys. When it returns from screen saver when I hit the return key these lights come on also.
