xgamma - Alter a monitor's gamma correction for XFree86 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 XFree86 X server video mode extension (XFree86-VidMode- Extension). 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. If no value for the gamma correction is given xgamma returns the current gamma correction of the display. -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. SEE ALSO
