Linux Mint 19.2 Xfceで.iccや.icmのインストール

How do you set system display color profiles in Xubuntu and Lubuntu?

If I was doing this first, without having set up Firefox I can open a terminal (ctrl+alt+t) and use colormgr to import my display profile from any location into ~/.local/share/icc/ like this

colormgr import-profile /home/user/Downloads/my_screen_profile.icc

Be careful with filenames. I had problems with white space in the filenames I created making the profiles with Argyll / DisplayCAL. It seemed best to keep the filenames short and simple. For some reason I have to run this command more than once. The first run copied the file into my icc directory, the second run actually imports the file into the colord system and reports back with a summary of the profile including meta and the profiles "object path". Next we can check that xiccd has allowed colord to interact with the display with the command

colormgr get-devices-by-kind display

This returns a summary which includes the display device's "object path" required for adding the profile with the command

colormgr device-add-profile "display device object path" "profile object path"

The object paths are long so I used shift+ctrl+c to copy and shift+ctrl+v to paste in my terminal window. If you run
colormgr get-devices-by-kind display

again you should see your profile in position 1) making it the default profile. If it isn't or you want to change the default use

colormgr device-make-profile-default "display device object path" "profile object path"

and removed with

colormgr delete-profile "display device object path" "profile object path"

Other options can be found from

colormgr --help
