Adjust brightness [software way]

xrandr --output LVDS1 --brightness 0.4
xrandr --output <outputname> --brightness <value> If the driver of your graphics card supports it, then you can use xrandr. The following command lists the current configuration: xrandr --current --verbose If you want to change the configuration of an output, then you need the name of the output. This name is part of the output of xrandr --current, for example LVDS1. The brightness can be changed like this: xrandr --output <outputname> --brightness 0.8 Gamma: xrandr --output <outputname> --gamma 0.5:1.0:1.0
