My monitor is not shown when I use Wayland instead of X11:

If however I login using X11 my monitor is correctly shown, and I can set my color profile.:

Bump… pretty please help me.

That’s the old X11 way of doing color management. On Wayland things work differently: you set an ICC profile in the Display and Monitor page in System Settings. Note that this is a Plasma 6-only feature.

To be clear, I know the color profile is to be selected/applied in Settings:Color Management. But my monitor is not shown when I log in using Wayland:

Color_Wayland
Color_Wayland1318×780 73 KB

Yet it shows correctly when I log in using X11:

Color_X11
Color_X111318×780 95.4 KB

The reason my initial post is the command colormgr get-devices is because I figured it was a better way of showing the issue, plus it gives more detailed information about my monitor. Probably I was wrong about that.

I think you’re looking in the wrong place. Look here:

Thank you, and I’m sorry I did not thoroughly read your original comment.

I cannot thank you enough. I have spent three hours trying to apply an ICC profile using the “Color Management” setting tab, when it obviously was in the “Display & Monitor” one. May the search engines show this reply instead of the millions of others that lead to dead ends.
