This argument is formated similar to the value printed by -@option{--get}, except it may end with zero, one, or two percent signed. -`+' is used for increase in brightness, `-' for decrease. Zero percent -signed is used for a raw value, one percent signed is used for a cooked -value that is usable on all backlight devices, and two percent signed -is used for a value relative to the current value. - -Assume the current backlight is 50 (25 %) on a device and the maximum is -200. @code{+25} will set it to 75 (37,5 %) and @code{-25} will set it to -25 (12,5 %). @code{+50%} will set it to 75 % (150), @code{-50%} would -set it to -25 % (-50) but because that is not within the accepted value -range it will be truncated to 0. @code{+100%%} will set it to 100 (50 %), -that it 200 % of the current brightness, @code{-50%%} will set it to -25 (12,5 %), that is 50 % of the current brightness. For the following -formats the `=' is optional if @option{-s} or @option{--set} is used. -@code{=150} will set the brightness to 150 (75 %), @code{=50%} will set -it to 50 % (100), and @code{=200%%} will set it to 100 (50 %), that is -200 % of the current brightness. - - - -@node Using -@chapter Using -@cindex interactive mode -@cindex usage -@cindex keyboard -@cindex darken screen -@cindex brighten screen -@cindex quit -@cindex exit -@cindex close -@cindex next screen - -When you run @command{adjbacklight} in interactive mode, the following -keys are used to adjust the backlighting: - -The @kbd{left} and @kbd{down} arrow keys are used to darken the screen. -The @kbd{right} and @kbd{up} arrow keys are used to brighten the screen. -@kbd{q}, @kbd{enter} and @kbd{<control>d} continues to the next backlight -controller, or if you are at the last one, exits the program. - - - -@node Behind the scenes -@chapter Behind the scenes -@cindex behind the scenes -@cindex inner workings - -On normally configured Linux systems, the kernel mounts a virtual -partition on @file{/sys}.
