Does anyone here know how to disable or suspend all display colour management? I’m trying make some display profiles with a measurement instrument and no matter what I do, Wayland or Xorg, there is a persistent icc profile in effect which gets regenerated from the EDID.

I can’t work out how to characterise the display without this profile being in effect, and unfortunately Displaycal and Argyll seem unable to disable it automatically.

Debian 13, GNOME 43

    I don’t know if this is still the case, but before Wayland came along, colord was the service that applied ICC profiles to a display. I’m not sure it still works on Wayland though. I feel like DisplayCal should be able to disable it, but you can too:

    sudo systemctl stop colord

      This sounds very convenient and I think Wayland does use colord - will give it a go 👍
