Z mana do xrandr:

„Please note that the gamma and brightness informations are only
approximations of the complete color profile stored in the server.”

„--brightness brightness
    […] this is a software only modification, if your hardware has
    support to  actually change the brightness, you will probably
    prefer to use xbacklight.”
