Hi,
darktable-cmstest reports the following below, ending with a warning about different profiles being attached to my 2 monitors. If I unplug the DELL monitor, the reporting profiles are correct for the one primary monitor. It’s annoying to have to unplug my second display when I want to use various color managed apps, so any pointers would be great. I have seen a few post about this but they are rather old and don’t seem to really address this issue.
Thanks.
System is

Better check your system setup
some monitors reported different profiles
You may experience inconsistent color rendition between color managed applications
To be honest, I’m very confused. Color management used to work, then a few system upgrades later then not so much. By profiles, I’m assuming the icc files. In desperation, I them into /usr/share/color/icc/colord, ~/.config/color/icc/devices/display, ~/.local/share/color/icc/devices/display/ and also in ~/.config/darktable/color. I’m still using X11.
A configuration management nightmare for sure.
Is there something else I should be looking at or configuring?
You need a program to load the X Atom Profile and make it available. Traditionally this has been xiccd and I believe displaycal will attempt to set the X Atom profile this way. But if you don’t have xiccd installed and running then the profile can not be set.
It is not a configuration nightmare if you listen and answer the questions posed instead of copying files everywhere.
I run fedora kde, but only one monitor. I would start with checking System Settings, Color Management. Ensure you apply the correct profile to each Device (Monitor).
So this is the darktable-cmstest result when the second (Dell) monitor is unplugged. It’s as it should be.

Your system seems to be correctly configured
But now, if I plug the second monitor back in, I get the profile mis-match again as indicated in the top message above.
As for the color profiles, the KDE color manager reports the correct profiles for both devices.
