I’m trying to get started with color management. I’m still trying to understand the topic and I might have some ideas confused.
A while ago I’ve bought a color munki and a refurbished display (dell u2413)
I’ve managed to generate some profiles for my display but the installation is never successful.
Something is wrong with colord and seems I’m not able to assign the newly generated profile for a device. Actually if I run ‘colordmgr get-devices’ I do not receive a list of device at all.
If I use the get-profiles subcommand instead I get a list of profiles (but they seems to be some kind of default system profiles) that does not include the one I’ve created.funny enough if I generate a profile for my laptop display I do not get an error message when I install the profile but the output of colordmgr are identical to the ones described above.
I’m on ubuntu 16.04 and I use i3wm as window manager. Is it possible that colord does not load the correct list of devices just because I’m not using kde or gnome?I’ve been trying to use anyway the profile (.icc file) with Geeqie. there is definitelly some difference when I enable the profile but the results I get are not what I expected. Colors are completely unnatural. especially the red tones looks to bright and radioactive.
I’ve tried to generate the profile a second time but results are similar.
Any advice on how to investigate the causes to both problems?colord needs support in the session to function (usually implemented via a daemon). Gnome and KDE have their respective implementations, for other desktop environments you can try xiccd.

In my case (DisplayCAL running on Manjaro Linux with Xfce desktop environment), ArgylCMS and the Profile Loader reports OK, but colord fails after “Querying for profile ‘icc…’ returned after 20 seconds.” Monitor profiles appear to be loaded by DisplayCAL as the display changes with different whitepoint choices, and Firefox (with gfx options set for colour management) passes various online tests for wide gamut images.
I tried installing xiccd from the AUR repository, but the DisplayCAL colord error report persists. So do I need to sort out the colord error, or is it just a warning?
it’s not a warning, it measn that colord is not aware of your profile.
you can use:
colormgr get-profilesto get the list of profiles currently known to colord (there might be many default profiles)
I think your problem is that it’s not sufficient to just install xiccd.. you also need to run it.
First of all, before you run xiccd you can test if colord knows about your devices and your profiles using the previous command and the following one:
colormgr get-deviceswithout xiccd running you should not get a list of devices (at least this was what I was experiencing)
Then you can execute xiccd (for the sake of this test you can run it in a shell.. but you might want it to be executed automatically by your windowmanager, be aware that it cannot be executed as a system demon but it has to be started in your X session https://github.com/agalakhov/xiccd/issues/20#issuecomment-400298256)
At this point you can check again the previous command. It should start returning the list of displays currently detected. (because xiccd is doing its job)
only after xiccd is running you can try to install the profile DisplayCal. this time it should work.
As a further double check.
You can run again the colormgr get-profiles to check that colord is now aware of the profile generated by DisplayCal.And colormgr get-device should now show you the profiles for each display the profile should appear there too.
