/etc/sddm.conf:
  ...
  # Path to a script to execute when starting the desktop session                                       
  SessionCommand=/usr/share/sddm/scripts/Xsession
  ...

/usr/share/sddm/scripts/Xsession:
  ...
  USERXSESSION=$HOME/.xsession
  ...
  if [ -f "$USERXSESSION" ]; then
    . "$USERXSESSION"
  fi

  ...
  and the solution seems to be adding

  dbus-update-activation-environment --systemd DBUS_SESSION_BUS_ADDRESS
  DISPLAY XAUTHORITY

  to .xinitrc or .xsession .

	A young married couple had their first child.  Their original pride
and joy slowly turned to concern however, for after a couple of years the
child had never uttered any form of speech.  They hired the best speech
therapists, doctors, psychiatrists, all to no avail.  The child simply refused
to speak.  One morning when the child was five, while the husband was reading
the paper, and the wife was feeding the dog, the little kid looks up from
his bowl and said, "My cereal's cold."
	The couple is stunned.  The man, in tears, confronts his son.  "Son,
after all these years, why have you waited so long to say something?".
	Shrugs the kid, "Everything's been okay 'til now".
