After upgrading my OpenSuSE 15.3 machine to 15.4, my monitor displays colors completely differently than before the upgrade. Apparently, the color calibration I had performed by using Argyll, DisplayCAL, and a Datacolor Spyder X has disappeared. Recalibrating failed because of a bunch of issues:
- OpenSuSE 15.4 no longer supports DisplayCAL. Obviously it's no longer maintained.
- Color management does exist in the KDE Control Center (under Hardware → Color correction), but doesn't work either. Instead of a color management module, only an error message is displayed: "you need Gnome color management installed in order to calibrate devices". But: I've already got
- I've found out that a particular program from Gnome's color manager is required:
gcm-calibrate. But: The official
gnome-color-managerpackage from OpenSuSE lacks this piece of software. Why?
About problem #2 there has been a bug filed at KDE, but without a solution or even a workaround: Bug #433068
Here's some system information:

I need a well-calibrated monitor as I do a lot of photo editing, so using an uncalibrated monitor is not an option for me. So: Is there an alternative method or color manager?
