Problem with DisplayCAL on KDE

Hello, You will need the colord package with the optional dependency of argyllcms that supports some calibration hardware, and colord-kde that will also add an menu entry in Settings. The error you get is about gnome-color-manager that need to be installed. Once you have that, the Settings Colord will show more options to handle the profiles.

I think it has some experimental support for wayland. Din’t test it.
