-Xcalib is simple and effective colour management software. It does one thing: adjust the colour profile of your display.

-Xcalib is a simple command. It adjusts the colour profile of your display, and that's all. If you are looking for a graphical control panel that claims to assist you to find the best gamma level based on your own perception, this is probably not the tool for you.

- 
-=====Install===== 
- 
-Install ''​xcalib''​ from [[http://​slackbuilds.org]]. 
- 
-=====Usage===== 
- 
-Xcalib has two use-cases: 
- 
-  * Load a pre-defined colour profile into your display. 
-  * Adjust the current colour profile of your display. 
- 
-**Load a Colour Profile** 
- 
-<WRAP indent> 
-To load a colour profile, just invoke xcalib along with the path to your colour profile: 
- 
-<​code>​ 
-$ xcalib /​usr/​share/​color/​icc/​eciRGB_v2_profile-2011/​eciRGB_v2_ICCv4.icc 
-</​code>​ 
- 
-Ideally, you will have created a colour profile for your monitor with a colour calibrator like [[http://​www.hughski.com/​|Color Hug]], or else managing colour profiles of your screen is probably not doing much good.  
- 
-To have this happen automatically upon boot, add that command to your ''​~/​.bash_profile''​ file. 
-</​WRAP>​ 
- 
-**Alter a Colour Profile** 
- 
-<WRAP indent> 
-Make fine adjustments to the current colour profile of your display with a trailing ''​-a''​ or ''​-alter''​ flag. For instance, to boost the blue levels of your current profile: 
- 
-<​code>​ 
-$ xcalib -blue 1.0 10.0 100.0 -a 
-</​WRAP>​ 
- 
-Which takes the blue at gamma level 1.0 (1 through 5 are valid), and sets its brightness to 10% and its contrast to 100%. 
- 
-To lower the blue in the current profile: 
- 
-<​code>​ 
-$ xcalib -blue 1.0 10.0 60.0 -a 
-</​code>​ 
- 
-Which takes the blue levels at 1.0 gamme and sets its brightness to 10% but its contrast to 60%. 
- 
-These settings can be done to ''​-red'',​ ''​-green'',​ or ''​-blue''​. 
- 
-Calibration alterations can be re-set with ''​-c''​ or ''​-clear'':​ 
- 
-<​code>​ 
-$ xcalib -c 
-</​code>​ 
- 
-To automate xcalib, add an xcalib command to your ''​~/​.bash_profile''​ file.
