Just running

/usr/lib/vino/vino-server should do the job.

Once you have access to your server, I would recommend that you add it to Autostarted Apps so it is always started.

You'll probably like change some settings with :

vino-preferences be very careful when you run vino-preference on a remote machine, if you uncheck "Allow other users to control your desktop", you won't be able to check it back.

or to edit :

~/.gconf/desktop/gnome/remote_access/%gconf.xml Here a sample file :

<?xml version="1.0"?> <gconf>

   <entry name="vnc_password" mtime="1289267042" type="string">

misc vnc notes

Goal

I would like to use VNC to access a Ubuntu 18.04 system from windows like I do with the Raspberry Pi.

• Connect to the existing desktop
• Keep the connection secure

This has been a bit of a struggle for a number of gotchas.

Overview

As I understand it ( may not have figured it out all the way )

• VNC has a server ( run on the machine you wish to view ) and viewer ( run on the machine you wish to access).
• In addition to having several components there are many versions of VNC. Directions for each differ, and differ across versions of Linux.
• I will focus on Tiger VNC and Ubuntu 18.04

New 'UbuntuBase-VB:1 (russ)' desktop at :1 on machine UbuntuBase-VB

Starting applications specified in /etc/X11/Xvnc-session Log file is /home/russ/.vnc/UbuntuBase-VB:1.log

Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/russ/.vnc/passwd :1 to connect to the VNC server.

russ@UbuntuBase-VB:~$ vncserver

loopback IP address is 127.0.0.1

not done yet ------

Start TigerVNC vncserver at boot

The ubuntu install package also registers a system service, making it easy to define listening vnc servers on startup. Edit the file /etc/default/vncserver and add the display number and user to start as:

sudo gedit /etc/default/vncserver

VNCSERVERS="1:myusername"

Then enable the service at boot with:

sudo update-rc.d vncserver defaults

---

end not done

vncserver in terminal to start

Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/russ/.vnc/passwd :1 to connect to the VNC server.
