I've just installed 16.04 on a new HP star wars laptop (a reskin of an HP pavillion I believe), but xset led 3 doesn't turn on the keyboard backlight.

Also there is no brightness slider or other brightness control for the screen.

This is the laptop with a skylake i5 CPU.

How can I fix this?


I chased around a few more links from the ones you gave Mohamed and found.....

I used the fix here to add a 20-intel.conf file and I now have a brightness slider and working keyboard shortcuts.

I found the fn key works backwards - by default the magic functions work, pressing the fn key means you get Fx key - this is the way the keyboard legends are marked tho'.

so kekyboard backlight can be switched on & off OK.
