Hi, I've just used dispcal to calibrate an additional external monitor, which connects to my laptop. I'm trying to work out how to activate the profile automatically.

Looking at System Settings > Hardware > Color (hey it's misspelt! ), I can only see my laptop's embedded display listed under devices. Is there a way to add the external monitor as well, rather than writing a udev rule + dispwin?

Does the external display appear in the output of "xrandr"?

Yes.

Is your system using colord or Oraynos for colour management?

I'm not sure what Oraynos is, but colord and colord-kde are installed.

Okay, I would suggest consulting the colord documentation to see if there is a way to determine if it is aware of the external display.
