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 the answer, but for troubleshooting, perhaps try to start a window manager / desktop environment without a display manager.

    Additionally, a simple window manager like sway perhaps.

      That’s an interesting idea - thanks. Perhaps a simple window manager would have no colour management to begin with. Will look into it 👍
