Although SSH allows users to establish connections with remote hosts, it only provides a command-line interface. Sometimes, it is more convenient to work in the graphical interface than the command line interface, or some work must be done in the graphical interface, then we can use VNC.

VNC (Virtual Network Computing) is an abbreviation for remote network computing. It can transfer the complete graphical interface to another computer's screen through the network. With the SSH connection established with the Raspberry Pi, follow the steps below to establish a VNC connection with the Raspberry Pi.

# Operation on Raspberry Pi

1、Install TightVNC software on Raspbian system

sudo apt-get install tightvncserver

2、Run the TightVNC server after installation, it will prompt you to enter a password.

tightvncserver

The following example starts a vnc session in full HD mode

vncserver :0 -geometry 1920×1080 -depth 24

# Control terminal operation

1、Install the VNC client on another computer, the following commands can be used on debian-like Linux systems:

sudo apt-get install xtightvncviewer

2、Establish a connection: Press ALT+F2, enter xtightvncviewer in the dialog box, and then enter the ip address and password of the remote computer.
