Bug 364361

I use an up to date Debian unstable, which has plasma-workspace 5.6.4.

I would like in my KDE environment to have notifications displayed by the notification daemon 'dunst'  http://www.knopwob.org/dunst/

Disabling notifications from the systray is not enough to stop KDE notification daemon, Notifications are not displayed any more, but seem still caught by the KDE notification daemon.
Trying to run dunst from the command line gives then:

$dunst 
Name Lost. Is Another notification daemon running?

I try to run dunst early, but when the desktop opens, there is no 'dunst' process anymore.

I have a similar output when I try to use notify-osd:
 $ /usr/lib/x86_64-linux-gnu/notify-osd
** (notify-osd:2893): WARNING **: Another instance has already registered org.freedesktop.Notifications
** (notify-osd:2893): WARNING **: Could not register instance



For the moment, the only way I found to make work another notification daemon is to comment out (most of) the source code in the
NotificationsEngine constructor and NotificationsEngine::registerDBusService()
in the file dataengines/notifications/notificationsengine.cpp  of plasma-workspace and rebuild the package.



Reproducible: Always


Actual Results:  
either notifications are displayed as plasma popups, or not displayed at all. 

Expected Results:  
I would like an option to disable completely KDE notification daemon (and unregister it from dbus).
Maybe there is a dbus magic invokation to do that? An option in the notification dialog from systray would be great.
