Sundown

Brightness Adjustment App, written in Vala

Instead of adjusting the backlight, this app uses xrandr to change the brightness of the image displayed on your screen. This can be useful for displays without an adjustable backlight, displays with a too-bright minimum, or too-dark maximum backlight, or OLED displays. Setups with multipe displays (maximum 4 displays) can also be adjusted with different brightness levels.
