Comment 2 for bug 765152

This bug is still in 16.10 present and a systemd problem.
Because of this bug Freecad is not able to use 3d mouse.
Workaround (in terminal):
sudo service spacenavd stop
sudo /usr/bin/spacenavd -v -d
start freecad

The error message:
failed to open X11 display ":0.0"
results in the lack of the magellan protocol and
freecad needs it.

Testet on x86_64(16.10) and Aarm64(Odroid C2, 16.04).
