SUMMARY

I have this problem on all of my Arch Linux systems, and they are installed at different time, one is only a few weeks old.
The problem is that the user service "xdg-portal-desktop-kde.service" starts before the service "xdg-portal-desktop.service".

I have tried to search on the web, but without any real luck.

STEPS TO REPRODUCE
1. Reboot the computer and login into a user
2. Run system "systemctl --user status plasma-xdg-desktop-portal-kde.service xdg-desktop-portal.service"

ADDITIONAL INFORMATION

My current workaround is to create the following 2 files:

/usr/lib/systemd/user/plasma-xdg-desktop-portal-kde.service.d/override.conf

```ini
[Unit]
Before=xdg-desktop-portal.service
Upholds=xdg-desktop-portal.service

[Service]
# Environment=QT_LOGGING_RULES=*.debug=true QT_DEBUG_PLUGINS=1

[Install]
WantedBy=plasma-workspace.target
```

/usr/lib/systemd/user/xdg-desktop-portal.service.d/override.conf

```ini
[Unit]
BindsTo=plasma-xdg-desktop-portal-kde.service
PartOf=plasma-xdg-desktop-portal-kde.service

[Service]
# Environment="G_MESSAGES_DEBUG=all"

Restart=on-failure
```

and enable the service `plasma-xdg-desktop-portal-kde.service` by running

```bash
systemctl --user enable plasma-xdg-desktop-portal-kde.service
```
