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
Iirc you can’t in gnome. You can create a color management profile that doesn’t do anything though but depending on what you’re trying to accomplish that might not be useful.
I’m saying the following as a literal lifelong linux user who has had to learn about color management and set it up in multiple environments: you will most likely be happier doing whatever you’re doing on a mac.
