Updated: xgamma 1.0.5
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Note that the xgamma utility is obsolete and deficient, xrandr should be used with drivers that support the XRandr extension.
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.
