xgamma - Alter a monitor's gamma correction through the X server

用法概要 /usr/bin/xgamma [-display display] [-screen screen] [-quiet] [-gamma f.f | [[-rgamma f.f] [-ggamma f.f] [-bgamma f.f]]] 描述 User Commands xgamma(1) NAME xgamma - Alter a monitor's gamma correction through the X server SYNOPSIS /usr/bin/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 correc- tion 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 Note that the xgamma utility is obsolete and deficient, xrandr should be used with drivers that support the XRandr extension.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 cur- rent gamma correction of the display. OPTIONS -display display This argument allows you to specify the server to connect to; see X(5). -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 sin- gle value, or separately for the red, green and blue components. This argument specifies the gamma cor- rection 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. X Version 11 Last change: xgamma 1.0.5 1 User Commands xgamma(1) ENVIRONMENT DISPLAY To get default host and display number. BUGS This client changes the internal values of the gamma correc- tion 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. SEE ALSO xvidtune(1), xrandr(1) AUTHORS Kaleb S. Keithley, X Consortium.
