Hi Sudheer, Yes, I had a similar use-case and faced the same problem. I ensured that my daemon was properly "osso-initialised" to ensure that its triggered properly by gui-app via dbus-daemon successfully.
But, in your use-case, you seem to use QT. I am not aware of the fix.

Not sure If I need to start a new thread but let me ask anyway. I have split my functionality into two apps, one running as a daemon and another as a GUI app. Now, I am trying send dbus signals to daemon. Till now I am not successful. Could you guys tell me what am I doing wrong here? Here is my /usr/share/dbus-1/services/org.maemo.vicar.service file content # Service description file [D-BUS Service] Name=org.maemo.vicar Exec=/home/user/vicar-daemon # Code from the cpp file if (!connection.registerService("org.maemo.vicar")) { qDebug() << dbusUtility.getErrorMessage(); exit(1); } if (!connection.registerObject("/org/maemo/vicar", this, QDBusConnection::ExportScriptableSlots)) { qDebug() << dbusUtility.getErrorMessage(); exit(2); } 1) If I reboot the device, the service does not get activated automatically. I verified this by running the method call org.freedesktop.DBus.ListNames (on System Bus). But If I run the executable manually, the service is registered successfully to system bus and I can see the name listed with the method call org.freedesktop.DBus.ListNames. Why is the daemon not launched automatically? 2) The daemon app connects to a custom signal on launch. QDBusConnection connection = QDBusConnection::systemBus(); bool success = connection.connect(QString(""), QString(""), QString("org.maemo.vicar"), QString("startOutgoingCallMonitor"),this, SLOT(startOutgoingCallMonitor())); I am receiving the boolean value as successful. With the app running, I tried to send the Dbus signal from terminal. I am not successful so far. Could you tell me what is wrong here? ~ $ dbus-send --system --print-reply --type=signal --dest=org.maemo.vicar org/maemo/vicar org.maemo.vicar.startOutgoingCallMonitor process 1686: arguments to dbus_message_new_signal() were incorrect, assertion "_dbus_check_is_valid_path (path)" failed in file dbus-message.c line 1165. This is normally a bug in some application using the D-Bus library. Couldn't allocate D-Bus message
