Overview
The tool loads ’vcgt’‐tag of ICC profiles to the server using the XRandR/XVidMode/GDI Extension in order to load calibrate curves to your graphics card.
Options
Set basic parameters
-d|--display STRING host:dpy
-s|--screen NUMBER Screen Number
-o|--output NUMBER Output Number
It appears in the order as listed in xrandr tool.
-a|--alter Alter Table
Works according to parameters without ICC Profile.
-n|--noaction Do not alter video-LUTs.
Work's best in conjunction with -v!
-p|--printramps[=FORMAT] Print Values on stdout.
-p TEXT # TEXT
-p SVG # SVG
-l|--loss Print error introduced by applying ramps to stdout.
-c|--clear Clear Gamma LUT
Reset the Video Card Gamma Table (VCGT) to linear values.
Assign
xcalib ICC_FILE_NAME
ICC_FILE_NAME File Name of a ICC Profile
Clear
xcalib -c -d STRING -s NUMBER [-o NUMBER] [-v]
-c|--clear Clear Gamma LUT
Reset the Video Card Gamma Table (VCGT) to linear values.
Invert
xcalib -i -d STRING -s NUMBER [-o NUMBER] [-v] [-n] [-p[=FORMAT]] [-l] ICC_FILE_NAME | -a
-i|--invert Invert the LUT
