Legion Y720 Keyboard backlight not working on Ubuntu Linux

I install Ubuntu 16.04 and the Keyboard backlight not turn on with Fn + Space.

 

Adding ideapad_laptop to blacklist with: sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop", not turn on too.

Fn+Space is controlled using a utility IHC.exe which is in a windows (Program Files) folder HIDKB.

 

If this tool/software is incompatible with Linux, I doubt your backlight keys will work.

Let me know if you find that folder and are able to use it for Linux. Thanks.
