[Thomas Anderson]

Binary package hint: spacenavd

spacenavd is not working log file is:

Spacenav daemon 0.5
using device: /dev/ttyS0
trying to open X11 display ":0.0"
   XAUTHORITY=/root/.Xauthority
No protocol specified
failed to open X11 display ":0.0"
waiting for X socket file to appear

can be worked around with:
sudo xhost +
sudo /etc/init.d/spacenavd restart

log file should look like:

Spacenav daemon 0.5
using device: /dev/ttyS0
trying to open X11 display ":0"

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).

Status changed to 'Confirmed' because the bug affects multiple users.

on Ubuntu 16.04
- symlinking root/.[X|ICE]authority with the user's, running 'xhost +' and starting spacenavd manually with sudo gives the same results : unable to open display.

>> spacenavd works fine compiled from source on Debian 8 (2017-03-07), with addition of a udev rule, running as root at startup with a simple script in /etc/init.d/

Shouldn't /lib/systemd/system/spacenavd.service be transformed into a user service using the new PartOf=graphical-session.target ?
