Need GDBus Service file for org.gnome.Shell

[Bazon Bloch <bazonbloch arcor de>]

Hello world:

SHORT VERSION:

I got the Error: 

"GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.Shell was not provided by any service files" 

and indeed, in  /usr/share/dbus-1/services there is no service file for org.gnome.Shell. 

Looking at the other files there, making such a file seems not so hard (just 3 lines, e.g. [D-BUS Service]   Name=org.freedesktop.ColorHelper    Exec=/usr/lib/colord/colord-session), but I don't know what to put in the "Exec=" line. I tried Exec=/usr/bin/gnome-shell, but that didn't work. 

So can someone please tell me how to make a working gdbus service file for org.gnome.Shell?

Thanks!

LONG VERSION:

I still got the flat-CPU-graph-problem with https://extensions.gnome.org/extension/120/system-monitor/ after resume from suspend. Thanks to this list, I now how to restart that via dbus:

gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell --method org.gnome.Shell.Extensions.ReloadExtension system-monitor paradoxxx zero gmail com

That works fine. 

I would like to have this executed automatically about 10s after each resume, and so I created a systemd service:

[Unit]

Description=User resume actions

After=suspend.target

[Service]

User=%I

Type=simple

Environment=DISPLAY=:0

ExecStart=/usr/bin/sh -c "/path/to/reload-sys-mon.sh"

[Install]

WantedBy=suspend.target

where the script reload-sys-mon.sh is just:

#!/bin/bash

sleep 10s && gdbus call --session --dest org.gnome.Shell --object-path /org/gnome/Shell --method org.gnome.Shell.Extensions.ReloadExtension system-monitor paradoxxx zero gmail com

exit 0

unfortunately, this service doesn't work:

$ sudo systemctl status resume bazon

resume bazon service - User resume actions

Jun 20 10:53:08 cookbook sh[1548]: Error: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.Shell was not provided by any service files

And so I need a service file to make that work. (Whyever it runs without that directly from terminal..)

Could someone please tell me how to create such a gdbus service file?

Thank you!
