Qubes in dual head - applying ICC profiles to only one screen

[daltong defourne]

So I have dual head config with qubes both at home and at work now (yay)

One of the monitors at work is a finnicky little thing that needs calibration. I have successfully made an ICC profile in windows (dual boot system) using a borrowed Spyder.

Now, I want to apply the ICC profile inside qubes.

I have googled about xcalib and it installed in dom0 successfully but I don't understand where to get monitor ID from (I want the ICC profile only applied to one monitor and not like, the entire qubes "screen/desktop" because, well, the second monitor is IPS and has okay color out of the box)

Please help :)
