Trying to understand freedesktop registration process?

Hi,

Prefacing by saying, low prio, afaik not a urgent matter, just thought i'd use some brain power on yellow journalctl logs...

The system works, yet there are minor errors on the backend of things.

I'm trying to understand the process here:

 Feb 21 16:27:53 ArchGa 
ksmserver[1571]: 
Failed to register with host portal 
QDBusError("org.freedesktop.portal.Error.Failed", 
"Could not register app ID: App info not found for 'org.kde.ksmse>

If I were to translate into my understanding:

ksmserver failed to register with host portal. When I look at PPID I find systemd.

Host portal is in this case?

Client portal (me?) would be using `xdg-desktop-portal` as confirmed by installed package `pacman -Qi`.

And ksmserver is a binary that is in charge of KDE session manager invent.KDE.org - Plasma Workspace

The devs of ksmserver would need to follow appropriate steps as per flatpak github page?

Therefore not much to do from a _users_ perspective?


Progressing to learn

You'd "need" an implementation so likely https://archlinux.org/packages/extra/x8 … ortal-kde/ but ksmserver is the session process and even if you've a portal implementation present (and starting) will likely just run ahead of it.
And I've a hard time seeing how ksmserver would require any portal features (it's relevant for flatschpak and is commonly used to augment that omissions in the wayland protocol to facilitate anything that resembles a functional desktop on wayland)
