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