I have a Thinkpad W520 and it has a Pantone colour calibrator.I looked it up here and in Google Search but as it seems the gnome colour manager can't use it as calibrating device at all(maybe there is no driver at all to do so,but anyway this is not the key issue). So I was wondering if there is any other colour calibrating hardware(from Pantone or any other decent company) which will be compatible with Ubuntu.There is I am asking this is because I have noticed that in Windows 7 where the Pantone colour calibrator of my laptop works,the eye strain is not happening so often it when it happens it usually is noticeable after a 2-3 hours where in Ubuntu I get it usually after 40 minutes of continuous use.
If by the way there is a way to make Ubuntu to use the colour of the laptop if you do not mind please explain to avoid any additional expenses from the purchase of a new colour calibration hardware.
