From: "Jasper St. Pierre" <[email protected]> The GIGABYTE GB-BXBT-2807 is a mini-PC which uses off the shelf components, like an Intel GPU which is meant for mobile systems. As such, it, by default, has a backlight controller exposed.
Unfortunately, the backlight controller only confuses userspace, which sees the existence of a backlight device node and has the unrealistic belief that there is actually a backlight there! Add a DMI quirk to force the backlight off on this system.
