I can see no way to perform colour management. In Ubuntu (proper), colour management is built into the gnome shell. I am getting into photography and have hit a bottleneck in that I can't calibrate my display and install colour profiles.
I see Wimpy added DisplayCal and dispcalgui to the boutique in 18.04 (I read it in another thread) but I see nothing for 20.04.
I see colord is installed by default.
Can anyone advise.
