    xrandr: fix brightness to prevent gamma to overflow and to allow 0
    
    With the new brightness option, gamma would overflow with values > 1,
    leading to rainbow looking screen.
    
    In addition, have the brightness by default to 1, so that specifying 0
    actually does the expected behaviour of leading to a black screen.
