VNC Viewer

A VNC session can function on any type of operating system that is installed on the server or client computer. VNC also supports sessions with iOS and Android devices. An essential element of the VNC viewer is the remote framebuffer (RFB) protocol. Its purpose is to transmit the VNC server’s screen content as well as the local client’s input. VNC remote access software, support server and viewer software for on demand remote computer support. Remote desktop support software for remote PC control.

RealVNC Comments

Sometimes it is not convenient to work directly on the Raspberry Pi. Maybe you would like to work on it from another device by remote control.

VNC is a graphical desktop sharing system that allows you to remotely control the desktop interface of one computer (running VNC Server) from another computer or mobile device (running VNC Viewer). VNC Viewer transmits the keyboard and either mouse or touch events to VNC Server, and receives updates to the screen in return.

You will see the desktop of the Raspberry Pi inside a window on your computer or mobile device. You'll be able to control it as though you were working on the Raspberry Pi itself.

VNC Connect from RealVNC is included with Raspberry Pi OS. It consists of both VNC Server, which allows you to control your Raspberry Pi remotely, and VNC Viewer, which allows you to control desktop computers remotely from your Raspberry Pi should you want to.

You must enable VNC Server before you can use it: instructions for this are given below. By default, VNC Server gives you remote access to the graphical desktop that is running on your Raspberry Pi, as though you were sitting in front of it.

However, you can also use VNC Server to gain graphical remote access to your Raspberry Pi if it is headless or not running a graphical desktop. For more information on this, see Creating a virtual desktop, further below.

Installing VNC

VNC is already installed on the full Raspberry Pi OS image, and can be installed via Recommended Software from the Preferences menu on other versions.

If you are not using a desktop you can install it from the command line as follows:

Enabling VNC Server

You can do this graphically or at the command line.

Enabling VNC Server graphically

• On your Raspberry Pi, boot into the graphical desktop.

• Select Menu > Preferences > Raspberry Pi Configuration > Interfaces.

• Ensure VNC is Enabled.

Enabling VNC Server at the command line

You can enable VNC Server at the command line using raspi-config:

Now, enable VNC Server by doing the following:

• Navigate to Interfacing Options.

• Scroll down and select VNC > Yes.

Connecting to your Raspberry Pi with VNC Viewer

There are two ways to connect to your Raspberry Pi. You can use either or both, depending on what works best for you.

Vnc Viewer Mac

Establishing a direct connection

Direct connections are quick and simple providing you're joined to the same private local network as your Raspberry Pi. For example, this might be a wired or wireless network at home, at school, or in the office.

• On your Raspberry Pi (using a terminal window or via SSH) use these instructions or run ifconfig to discover your private IP address.

• On the device you'll use to take control, download VNC Viewer. For best results, use the compatible app from RealVNC.

• Enter your Raspberry Pi's private IP address into VNC Viewer:

Establishing a cloud connection

You are entitled to use RealVNC's cloud service for free, provided that remote access is for educational or non-commercial purposes only.

Cloud connections are convenient and encrypted end-to-end. They are highly recommended for connecting to your Raspberry Pi over the internet. There's no firewall or router reconfiguration, and you don't need to know the IP address of your Raspberry Pi, or provide a static one.

• Sign up for a RealVNC account here: it's free and it only takes a few seconds.

• On your Raspberry Pi, sign in to VNC Server using your new RealVNC account credentials:

• On the device you'll use to take control, download VNC Viewer. You must use the compatible app from RealVNC.

• Sign in to VNC Viewer using the same RealVNC account credentials, and then either tap or click to connect to your Raspberry Pi:

Authenticating to VNC Server

Vnc Viewer Ubuntu

To complete either a direct or cloud connection, you must authenticate to VNC Server.

If you're connecting from the compatible VNC Viewer app from RealVNC, enter the user name and password you normally use to log in to your user account on the Raspberry Pi. By default, these credentials are pi and raspberry.

If you're connecting from a non-RealVNC Viewer app, you'll first need to downgrade VNC Server's authentication scheme, specify a password unique to VNC Server, and then enter that instead.

• If you are in front of your Raspberry Pi and can see its screen, open the VNC Server dialog on your Raspberry Pi, select Menu > Options > Security, and choose VNC password from the Authentication dropdown.
• Or if you're configuring your Raspberry Pi remotely from the command line, then to make the changes for Service Mode (the default configuration for the Raspberry Pi):
  • Open the /root/.vnc/config.d/vncserver-x11 config file.
  • Replace Authentication=SystemAuth with Authentication=VncAuth and save the file.
  • In the command line, run sudo vncpasswd -service. This will prompt you to set a password, and will insert it for you in the right config file for VNC Server running in Service Mode.
  • Restart VNC Server.

Playing Minecraft and other directly rendered apps remotely

You can remotely access apps which use a directly rendered overlay, such as Minecraft, the text console, the Raspberry Pi Camera Module, and more.

To turn this feature on:

• On your Raspberry Pi, open the VNC Server dialog.

• Navigate to Menu > Options > Troubleshooting and select Enable experimental direct capture mode.

• On the device you'll use to take control, run VNC Viewer and connect.

  Note: existing connections must be restarted in order for these changes to take effect.

Please note that direct screen capture is an experimental feature. Chrome password manager vs 1password. If you're connecting from a desktop computer and mouse movements seem erratic, try pressing F8 to open the VNC Viewer shortcut menu and selecting Relative Pointer Motion.

If performance seems impaired, try these troubleshooting steps, or let RealVNC know.

Creating a virtual desktop

If your Raspberry Pi is headless (i.e. not plugged into a monitor) or controlling a robot, it is unlikely to be running a graphical desktop.

Tight Vnc Viewer For Windows 10

VNC Server can create a virtual desktop for you, giving you graphical remote access on demand. This virtual desktop exists only in your Raspberry Pi's memory:

Vnc Viewer Download

To create and connect to a virtual desktop:

• On your Raspberry Pi (using Terminal or via SSH), run vncserver. Make note of the IP address/display number that VNC Server will print to your Terminal (e.g. 192.167.5.149:1).

• On the device you'll use to take control, enter this information into VNC Viewer.

To destroy a virtual desktop, run the following command:

Vnc Viewer Raspberry Pi

This will also stop any existing connections to this virtual desktop.
