Hi,

The backlight control doesn't work under Ubuntu 18.04.
Does anyone know how to make backlight control work?
My model is G9-593-77WF (Nvidia 1070).

Thanks.

    I don't use ubuntu but do use a different distro and sounds like a keyboard shortcut missing for that action.  Have a dig around the keyb shortcuts 'cause it might have been mis-mapped on install (I've had similar over the years for display backlight controls and keyb backlight control too).

    I have fixed the issue myself.
    The solution is
    1. Install latest nvidia driver
    2. Use xbacklight -set [0-99]
