Journal messages include many QDBusError("org.freedesktop.portal.Error

I have noticed that after recent updates I am getting quite a lot of lines in the journal log like these:

Oct 20 12:48:55 lenovo1 kactivitymanagerd[1121]: Failed to register with host portal QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID: App info not found for 'org.kde.ActivityManager'")

Does anyone know if this is benign or if action is needed to fix configs or other remedial changes are required?

https://bbs.archlinux.org/viewtopic.php?id=312301
https://discuss.kde.org/t/failed-to-reg … iled/43117

Also https://bbs.archlinux.org/viewtopic.php?id=315215

0. nb. those are different messages and (technically) problems
1. it's super common
2. xdg-desktop-portal is half-assed trash out of the flatschpak-verse
3. autostarting via systemd user service is non-deterministic, convoluted and fragile

The messages in and by themselves are just noise, it becomes a problem if a service actually has a meaningful connection issue that won't stick out from the generic noise.

kactivitymanagerd, gmenudbusmenuproxy and the akonadi workers will hardly need an Äpp Info, except to silence this.
org_kde_powerdevil, kded6, kmix, kaccess, ksplashqml & plasmashell are probably several modules in the same process (check qdbus6 to see along what other interfaces they show up w/ the same address)

And

Oct 20 12:48:55 lenovo1 xdg-desktop-portal-kde[1481]: Failed to register with host portal QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID: Connection already associated with an application ID")

is just hilarious…

Brave new world.

OK - thanks- so it is just noise and I can grey out any lines I see! Though it would be nice to have a cleaner log file and not have the cpu wasted chewing on things not needed.

The "logging culture" is gone since upcoming systemd and it's own implementing of the various distributed bus systems...

Nothing more respects things like loglevels or facilities.
The user-journal under environments like plasma/kde has mutated to an trash can.

ex: "plasmashell[5524]: QGridLayoutEngine::addItem: Can't add Body_QMLTYPE_265(0x559c8c651b20, id="bodyLabel", parent=0x7f4f64730fb0, geometry=0,0 532.516x54) at cell (1, 0) because it's already taken by Summary_QMLTYPE_272(0x559c8bbabbf0, id="summary", parent=0x7f4f64730fb0, geometry=0,0 175.828x21)"

WTF? Fix it or be quiet! Developers: Read your own output and fix it instead making a round corner a little bit rounder... ;-)

Ever since Windows NT and later versions, with their cryptic system logging, Linux users have been able to proudly showcase sensible, comprehensible logging. Unfortunately, those days are long gone. We're currently turning back the clock.
