I recently switched to Linux. I thought I would use displayCAL to calibrate my screen but it turns out that it requires python 2.7 and won’t install on Ubuntu 20. I have looked at ArgyllCMS but that looks a little intimidating. Makes me wonder what other people are using.
There is a flatpak of displaycal available.

Hello, Anders Torger made a very good manual for screen calibration with argyll, the command line version.

Look at the Workflow summary at the end of that long document. Works very well.

There is also this:
It’ a Debian Buster live system that includes Displaycal. It has a newer kernel.

I found these instructions on this website: PIXLS.US - Display Color Profiling on Linux
I have followed them and they produced an ICC which seems to work. Not sure how good the calibration is but at least it;s something. Will look at the site you linked to and compare instructions.
It is also possible to use an older Ubuntu Version to generate the .icc and later it can be imported. Just choose an older Ubuntu image version, start it as a live distribution and install DisplayCAL, like it is suggested in the Mastodon post with Debian. After that save the icc file, restart your system and reboot your system. This works fine for me the last time I’ve tried it.
But the easiest solution will probably be to use the Flatpak version.

As the flatpak is offical now since a few days installing it is the easies thing to do and my live system is deprecated.

That is excellent news, a flatpak for Displaycal!
I didn’t have an issue installing the ubuntu package of Displaycal on my Mint 20 machine, once I installed python2.7-minimal, but certainly having the flatpak available for Displaycal now makes things easier going forward, especially as it looks likely more distros will be removing Python2 from their repositories going forward.
I’ve installed and run the DisplayCAL flatpak. The calibration went smoothly and I clicked “Install profile”. The profile did not install and is nowhere to be found on the drive. There is no folder “.local/share/DisplayCAL/storage”
Any ideas? Thanks. I’m on Kubuntu 20.04.
Problem solved. The .icc profile was not where I expected, but rather in
.var/app/net.displaycal.DisplayCal/data/DisplayCal/storage
I was able to find it by starting up DisplayCal again and it showed the location. Then I copied it to my desktop so I can apply it to individual apps.
Yes, .var/app is the canonical flatpak settings location.

Hello, on my Xubuntu 20.04.3 system, the profiles generated by DisplayCAL are stored in ./local/share/DisplayCAL/‘generated profile’, in my case it’s called “EA231WMi #1 2020-01-02 09-42 D6500 2.2 VF-M XYZLUT+MTX”.

It seems that in KDE, Dolphin won’t search in the hidden folders. Kfind does work for this though, in this case I was able to search for *.icc or just the first few letters of the name of the profile.
