New description:

 ElCapitan with all ports up to date

 I installed xinit and xorg-server as advertised in ticket:42739 and
 rebooted but the following problem remains.

 ''--notification'' commands do not show a zenity dialog and report an
 error
 {{{
 zenity --notification --text "show me something."

 ** (zenity:2501): WARNING **: Error showing notification: The connection
 is closed
 }}}


 by contrast (but with a warning), I can run
 {{{
 zenity --info --text "show me something."
 Gtk-Message: GtkDialog mapped without a transient parent. This is
 discouraged.
 }}}

 Thanks for any hint to improve this
