Created attachment 165594 [details] Plasma 6 Wayland with colord-kde v24.01.95 SUMMARY kcm_colord KDE Plasma 6 Wayland doesn't show any display device. On KDE Plasma 5 Wayland and KDE Plasma 6 X11 display device is listed STEPS TO REPRODUCE 1. Open "System Settings" > "Connected Devices" > "Color Management" or launch "kcmshell6 kcm_colord" 2. On the Devices tab search for Display device on the list OBSERVED RESULT No Display devices EXPECTED RESULT Even on VM there should be display device SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Kinoite 40 (Rawhide) KDE Plasma Version: 5.93.0 KDE Frameworks Version: 5.249.0 Qt Version: 6.6.1 ADDITIONAL INFORMATION 1. Both KDE Neon User (Plasma 5) and Testing (Plasma 6) editions provide colord-kde v23.08.4, and there I see the same issue. So I don't think that it's a regression with QT6 port (version 24.01.90+), distro packaging issue etc. 2. ICC profile assignment with "System Settings" > "Input & Output" > "Display & Monitor" > "Display Configuration" works properly on KDE Plasma 6 Wayland. 3. On KDE Plasma 6 Wayland, printer appear in the list.

This is expected. colord is not used/relevant on Wayland (except for printers)
