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

You can create a color management profile that doesn’t do anything

That would actually be great! I need a completely un-managed baseline to build off. How is it done?

you will most likely be happier doing whatever you’re doing on a mac.

I have too much sunk cost fallacy with this now and cannot turn back. If you have any practical tips for survival please share them!

Uhh displaycal? I think is the program. Last I looked nothing worked right in Wayland or gnome, so if either of those are in your setup it’s worth getting rid of em.

You’re not gonna like my practical tip: generate a profile on Windows or mac computer and copy the profile to the linux machine.

I don’t know what you’re actually trying to accomplish so if that’s not absolutely secret squirrel shit maybe lay it out but my other advice is the same as the first verse: use a mac instead of trying to colorimeter a linux attached display. Unless you’ve shelled out for a very good monitor, use a mac with a built in display.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
