How to Set Up a VNC Server on Ubuntu 20.04

In this tutorial, we will explore how to install and set up a VNC server on Ubuntu 20.04 LTS. VNC, which stands for Virtual Network Computing, allows us to remotely access and interact with our devices graphically from anywhere in the world without requiring a VPN, port-forwarding, or firewall configuration.

Before we begin, make sure you have signed up for a free RealVNC Team account. This will provide you with the necessary credentials to access your devices remotely.

Step 1: Install RealVNC Server on Ubuntu 20.04

To install the RealVNC server, follow these steps:

1. First, update and upgrade your operating system using the following command: `sudo apt-get update && sudo apt-get dist-upgrade`

2. Once the updates are complete, download the arm64 package for RealVNC from the Raspberry Pi Foundation's site using the following command: `sudo dpkg -i realvnc-vnc-server_6.1_b`

Step 2: Configure the VNC Server

After installing the RealVNC server, you will need to configure it to allow remote access.

1. First, enable and start the VNC service using the following commands: `sudo systemctl enable vnc` and `sudo systemctl start vnc`

2. Next, add the necessary symlinks to the `/usr/lib/` folder by running the following commands:

```

sudo ln libcontainers.so /usr/lib/libcontainers.so.0

sudo ln libmmal_vc_client.so /usr/lib/libmmal_vc_client.so.0

sudo ln libmmal_util.so /usr/lib/libmmal_util.so.0

sudo ln libmmal_components.so /usr/lib/libmmal_components.so.0

sudo ln libmmal_core.so /usr/lib/libmmal_core.so.0

sudo ln libbcm_host.so /usr/lib/libbcm_host.so.0

sudo ln libvchiq_arm.so /usr/lib/libvchiq_arm.so.0

```

3. Finally, add the necessary files to the `/usr/lib/aarch64-linux-gnu/` folder by running the following commands:

```

cd /usr/lib/aarch64-linux-gnu/

sudo ln libvcos.so /usr/lib/libvcos.so.0

```

Step 3: Access Your Devices Remotely

Once you have completed these steps, you will be able to access your devices remotely using the VNC client software.

1. To connect to your device, open the VNC client software and enter the IP address of your device followed by the port number (default is 5900).

2. Enter your RealVNC credentials to authenticate and gain access to your device.

With these steps complete, you will be able to remotely access and interact with your devices graphically from anywhere in the world without requiring a VPN, port-forwarding, or firewall configuration.
