23271	Instructions to test xfce4-notifyd may fail	pierre	blfs-book	"In the book, we say to issue:
{{{
notify-send -i info Information ""Hello $USER, this is a test""
}}}
to test xfce4-notifyd after installing it. But there are several reasons why this may fail:
- DISPLAY is not defined in the systemd user environment. Then, since xfce4-notifyd is started by systemd, it cannot find the display and fails
- several .service files with the same bus name ""org.freedesktop.Notifications"" may be installed in /usr/share/dbus-1/services, and the wrong one may be used. An [https://github.com/systemd/systemd/issues/312 old thread] seems to conclude that the only way to avoid this is to remove the faulty file(s).

We should therefore decide how to modify the instructions so that the test does not fail in the above cases. We can either:
- tell the user to run:
  {{{
     systemctl --user set-environment DISPLAY=$DISPLAY
  }}}
  '''and''' to ensure that only one .service file containing Name=org.freedesktop.Notifications is in the services directory
- start the daemon before running the test:
  {{{
     /usr/lib/xfce4/notifyd/xfce4-notifyd &
  }}}
- remove the test altogether (we don't test other notify daemons in this way)

But we cannot leave the instructions as they are..."	enhancement	closed	normal	13.1	BOOK	git	medium	fixed
