 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.  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.

 +If you use multiple screens, us the ''​-s''​ flag. By default, ''​-s''​ is set to ''​0''​ to represent the primary screen. If you have two screens, for example, you may choose between ''​-s 0''​ and ''​-s 1''​.

 +There'​s a small chance that you might set your display as one big screen. If this is how you manage your display, then both physical monitors are treated as one "​screen",​ so ''​xcalib''​ would impose the same profile to both. To change that behaviour, change your display settings in KDE System Settings.
  
 To have this happen automatically upon boot, add that command to your ''​~/​.bash_profile''​ file. To have this happen automatically upon boot, add that command to your ''​~/​.bash_profile''​ file.

 +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
 +</​code>​
  
 +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.
