To test this, I used the darktable-cmstest utility which comes with the darktable photo editor. While both profiles were installed Ok and colord has become aware of them, one problem persisted: the X atom didn't return the same profile. Calibrated and profiled my screens with Displa圜AL/Argyll, acquired two ICC profiles for them, and imported these into the "Color" settings tab appropriately.deb (for Ubuntu 19) and installed it, it worked Ok on 20.04. Found the (ancient and probably abandoned) Displa圜AL 3.8.9.3.Downloaded the latest Argyll binary distribution, v.2.3.1, unpacked it and made binaries accessible for launch from shell prompt.On 20.04 the SpyderX wasn't supported natively by Ubuntu, so my steps were I just upgraded to Ubuntu 22.04 from 20.04 and wish to use my SpyderX colorimer to calibrate my two displays (one is laptop built-in, the other is Philips 273V on HDMI).
