Hello, on Fedora GNOME Xorg session, I am using

$ dbus-send --print-reply --dest=org.gnome.Mutter.IdleMonitor
/org/gnome/Mutter/IdleMonitor/Core
org.gnome.Mutter.IdleMonitor.GetIdletime

to retrieve the user idle time. Indeed I get message

method return time=1558965539.579835 sender=:1.19 ->
destination=:1.97 serial=409 reply_serial=2
uint64 17

But if I try to use gdbus command

$ gdbus call --system --dest org.gnome.Mutter.IdleMonitor
--object-path /org/gnome/Mutter/IdleMonitor/Core --method
org.gnome.Mutter.IdleMonitor.GetIdletime

The org.gnome.Mutter name is not on the system bus, since it's your compositor's instance and it's running in your session.

The default for `dbus-send` is to use the session bus. The equivalent for `gdbus` is to use the `--session` argument; you're using `--system`, which is meant for the system bus.

For instance, this:

```

$ gdbus call --session \

> --dest org.gnome.Mutter.IdleMonitor \

> --object-path /org/gnome/Mutter/IdleMonitor/Core \

> --method org.gnome.Mutter.IdleMonitor.GetIdletime
(uint64 29,)
```

will return the appropriate result with no warnings.
