Backlight keyboard activation on Asus Strix

How can i activate the backlight keyboard on my nb (Asus Strix Republic of Games) ?

Using Win10 the backlight is active and can be deactivated using FN-F3/FN-F4 but with ubuntu (i am using the Lubuntu desktop environment) the FN key seems not to be active and the backlight keyboard is always off.
