vino-server does not autostart on Ubuntu-GNOME

[Florian Apolloner]

Impact
======
The Desktop Sharing option in GNOME's Settings apps silently doesn't work.

Test Case
=========
On the host computer:
1. In Ubuntu GNOME, open the Settings app.
2. Open the Sharing panel.
3. In the headerbar, turn on Sharing.
4. Click Screen Sharing. Turn it On. (If it was already On, turn it off then On.)

On the guest computer:
5. From a different computer connected to the same local network, attempt to connect to the host computer.

For this, you can install Vinagre. Click Connect. Use Protocol: VNC and enter the IP address for the test computer in the Host: field. Click Connect.

On the host computer:
6. You probably need to approve a popup message to allow the remote user to connect.

Regression Potential
====================
This only adds a symlinked NoDisplay=true .desktop to
/usr/share/applications/

Other Info
==========
The fix for Ubuntu 16.10 is a bit different. There we can just backport the systemd service file added to vino 3.22 since gnome-settings-daemon 3.22 handles sharing services via systemd user services.

I verified that the extra .service file does not affect the way vino-preferences works in Unity 16.10. It's just ignored and manually trying to start the service in Unity doesn't work either which is fine. For 17.04+ we should look at having Unity use the systemd user service too.

Original Bug Report with Workaround
===================================
Running gnome-settings-daemon -r --debug shows that it tries to locate vino-server.desktop which it cannot find and therefore fails to start. Looking at the debian package, a confirmed and working fix for Ubuntu 16.04 is: sudo ln -s /etc/xdg/autostart/vino-server.desktop /usr/share/applications/vino-server.desktop or only shipping that file in /usr/share/application

I currently don't have access to any Ubuntu boxes, but will try as soon as I get access to one again.

[Sebastien Bacher (seb128)]

Did you have a chance to try that one?

[Florian Apolloner (apollo13)]

Sadly no, we switched to Unity for new deployments due to other issues. I currently do not run Gnome anymore on Ubuntu 16.04 :( But from looking at the diff, the patch should be okay -- when I tried it I actually symlinked it to see if it actually fixes it.
