I've tried them all: lightdm, sddm and slim but it did not make
any difference for this bug.

Hi,
yes this looks the same due to plasma-desktop being installed
and if I recall correctly notifications were working before
installing it.

I did try other notification services: dunst and growl that did work, but they do not integrate well
with xfce's notification settings.

Removing /usr/share/dbus-1/services/org.kde.plasma.Notifications.service don't seem a viable option to me.

I cannot believe that this dbus services are started alphabetically without checking if they belong
to the current DE...

Other solutions I can think off:
1) use a system wide notification daemon for all DE's, rather complicated needs work to integrate well.
2) start the daemons in /etc/xdg/autostart where they can be selected correctly with
    NotShowIn=GNOME;KDE;Unity;MATE; etc.
    this is a minor change that could be attempted even at devuan level to ensure that different DE's
    installed play along nice.
I will test n.2 and report.
