Install TigerVNC -
$ sudo apt install tigervnc-standalone-server
Configure VNC Server by running
$ vncserver
This will setup a password to access the server through a remote session.
Create new /etc/vnc directory -
$ sudo mkdir /etc/vnc
Create a new file /etc/vnc/startup with these lines -
#!/bin/sh
test x"$SHELL" = x"" && SHELL=/bin/bash
test x"$1" = x"" && set -- default
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
vncconfig -iconic &
"$SHELL" -l << EOF
export XDG_SESSION_TYPE=x11
export GNOME_SHELL_SESSION_MODE=ubuntu
dbus-launch --exit-with-session gnome-session --session=ubuntu
EOF
vncserver -kill $DISPLAY
Make the /etc/vnc/xstartup file executable -
$ sudo chmod +x /etc/vnc/xstartup
Create/add this file ~/.vnc/xstartup with the following contents -
#!/bin/sh
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
Make the file executable -
$ chmod +x ~/.vnc/xstartup
Create a new service file to configure VNC Server to startup as a service on boot -
$ sudo vi /etc/systemd/system/vncserver@service
Add the following to the contents of the newly created file -
[Unit]
Description=Start TigerVNC server at startup
After=syslog.target network.target
[Service]
Type=forking
User=someuser
Group=someuser
PAMName=login
WorkingDirectory=/home/someuser
PIDFile=/home/someuser/.vnc/%H:590%i.pid
ExecStartPre=-/bin/sh -c "/usr/bin/vncserver -kill :%i > /dev/null 2>&1"
ExecStart=/usr/bin/vncserver -fg -depth 24 -geometry 1280x800 -localhost no :%i
ExecStop=/usr/bin/vncserver -kill :%i
[Install]
WantedBy=multi-user.target
Update the permissions of the newly created file with
$ sudo chmod +x /etc/systemd/system/vncserver@service
Reload the daemons so that it can load the new VNC service -
$ sudo systemctl deamon-reload
Enable the VNC service so that it loads on boot -
sudo systemctl enable vncserver@1.service
Kill any existing VNC servers and start the service -
$ vncserver -kill :*
$ sudo systemctl start vncserver@1
Check the status of the service with -
$ sudo systemctl status vncserver@1
Add a new crontab by running
$ crontab -e
and adding
@reboot /usr/bin/vncserver -fg -depth 24 -geometry 1920x1080 -localhost no :1 &
