Re: Problems with colord & colormgr get-devices

Printers can also use color profiles, so seeing them in the output is normal .

Did you install ICC profiles for your displays ?

Yes, the printers in the list are OK. But no display is listed. Why?

https://wiki.archlinux.org/title/ICC_profiles#xiccd This is a good link. xiccd was not running on my system. After starting this deamon, my display is listed in the output of colormgr get-devices

But no display is listed. Why?

colord is designed by Gnome and only supported out of the box by Gnome & KDE.
