DELL XPS 7590 OLED brightness controll

Hi all

Do we have a way of controling OLED brightness ( or colour Gama) by actually using the brightness control keys ?

Thanks advance

If the keys aren’t working out if the box, you can still use key bindings to map them to something that is working like xbacklight.

Sometimes installing xfce4-power-manager or mate-power-manager will get the keys working like they’re suppose to.
