Backlight on keyboard

Asked by Mario

My backlight on my new MS-industrial fusion keaboard does not work on Ubuntu 14.10.However it does work during boot time and grub and it does work on Ubuntu 15.04 with unity8.However on unity 8 it works only after I aam logged in into unity 8.

Here are more details to the problem:

However if anyone from the development team is here reading this:Please try to fix this in 14.10 and not break it in Unity 8 :)

xset led 32

see man xset

       led The led option controls the keyboard LEDs. This controls the
               turning on or off of one or all of the LEDs. It accepts an
               optional integer, a preceding dash(-) or an 'on/off' flag. If
               no parameter or the 'on' flag is given, all LEDs are turned on.
               If a preceding dash or the flag 'off' is given, all LEDs are
               turned off. If a value between 1 and 32 is given, that LED
               will be turned on or off depending on the existence of a
               preceding dash. ``xset led 3'' would turn led #3 on. ``xset
               -led 3'' would turn it off. The particular LED values may
               refer to different LEDs on different hardware. If the X server
               supports the XKEYBOARD (XKB) extension, leds may be referenced
               by the XKB indicator name by specifying the `named' keyword and
               the indicator name. For example, to turn on the Scroll Lock
               LED:

               xset led named "Scroll Lock"
