xgamma
xgamma(1) General Commands Manual xgamma(1)NAME
xgamma - Alter a monitor's gamma correction through the X server
SYNOPSIS
xgamma [-display display] [-screen screen] [-quiet] [-gamma f.f | [[-rgamma f.f] [-ggamma f.f] [-bgamma f.f]]]
DESCRIPTION
xgamma allows X users to query and alter the gamma correction of a monitor via the X video mode extension (XFree86-VidModeExtension).
Note that the xgamma utility is obsolete and deficient, xrandr should be used with drivers that support the XRandr extension.
If no value for the gamma correction is given via the -gamma or -rgamma/-ggamma/-bgamma options, xgamma prints the current gamma correction
of the display.
OPTIONS -display display
This argument allows you to specify the server to connect to; see X(7).
-screen screen
When multiple displays are configured as a single logical display, this option allows you to select the screen you wish to change.
-quiet Silence the normal output of xgamma
-help Print out the `Usage:' command syntax summary.
-gamma f.f
The gamma correction can either be defined as a single value, or separately for the red, green and blue components. This argument
specifies the gamma correction as a single value.
-rgamma f.f
This argument specifies the red component of the gamma correction.
-ggamma f.f
This argument specifies the green component of the gamma correction.
-bgamma f.f
This argument specifies the blue component of the gamma correction.
ENVIRONMENT
DISPLAY To get default host and display number.
BUGS
This client changes the internal values of the gamma correction for the Xserver. Whether or not these values are respected depends on the
video drivers.
The gamma values are passed to the Xserver with 3 decimal places of accuracy.
