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
Probably nothing helpful as you are already way past my understanding. Maybe look at the Darktable documentation or even the “green lantern” stuff (IIRC the name). GL or (something) Lantern is/was an open source software for Canon cameras that breaks out all DSLR features on nearly any Canon camera.
Nearly a decade ago, I had a makeshift product photography studio and messed with Macbeth color charts and profiles matched to a monitor. The tutorial guides I followed were from these two projects IIRC. GL.
