Install x11vnc on xubuntu 16.04 for remote access

Tight VNC server opens new session, but if you need to connect to active session(like in teamviewer when user see what you are doing) I suggest to install x11vnc.
Installation process as follows:

sudo apt-get install x11vnc -y

next - specify password for remote connections:

sudo x11vnc -storepasswd /etc/x11vnc.pass

now create service unit file:

sudo touch /lib/systemd/system/x11vnc.service

and open it in editor:

sudo nano /lib/systemd/system/x11vnc.service

paste to file:

[Unit] 
Description=Start x11vnc at startup. 
After=multi-user.target
[Service] 
Type=simple 
ExecStart=/usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pass -rfbport 5900 -shared 
[Install] 
WantedBy=multi-user.target

 now configure service:

sudo systemctl enable x11vnc.service  
sudo systemctl daemon-reload

now reboot and try to connect to x11vnc.
