说明
xgamma queries and alters the gamma correction of a monitor via the XFree86-VidModeExtension. Gamma affects mid-tone brightness; values below 1.0 increase contrast while values above 1.0 decrease it. When invoked without gamma arguments, xgamma prints the current red, green, and blue gamma values to standard output. Gamma values are transmitted to the X server with three decimal places of precision. Separate control of red, green, and blue channels allows color temperature adjustment. Settings are temporary and reset on X server restart. For persistence, add xgamma commands to ~/.xinitrc or ~/.xprofile, or configure in xorg.conf. The DISPLAY environment variable provides the default host and display number.
