It uses the RandR extension to find all outputs on the X server
supporting backlight brightness control and changes them all in the
same way.

.SH NAME
xbacklight \- adjust backlight brightness using RandR extension
.SH SYNOPSIS
.B "xbacklight"
[-help]  [-display \fIdisplay\fP]
[-get]
[-set percent]
[-inc percent]
[-dec percent]
.SH DESCRIPTION
.I Xbacklight
is used to adjust the backlight brightness where supported. It finds all
outputs on the X server supporting backlight brightness control and changes
them all in the same way.
.IP -get
Print out the current backlight brightness of each output with such a
control. The brightness is represented as a percentage of the maximum
brightness supported.
.IP "-set \fIpercent\fP"
Sets each backlight brightness to the specified level.
.IP "-inc \fIpercent\fP"
Increases brightness by the specified amount.
.IP "-dec \fIpercent\fP"
Decreases brightness by the specified amount.
.IP -help
Print out a summary of the usage and exit.
.IP "-time \fImilliseconds\fP"
Length of time to spend fading the backlight between old and new value.
Default is 200.
.IP "-steps \fInumber\fP"
Number of steps to take while fading. Default is 20.
.SH "SEE ALSO"
