How to Install VNC Server on Ubuntu 18.04

Installing a VNC server on your Ubuntu 18.04 system allows you to remotely access and control your machine from another device. In this tutorial, we will show you how to set up an x11vnc server on your Ubuntu system and connect to it using a VNC client.

Step 1: Start x11vnc Manually

Before setting up the auto-start feature for x11vnc, let's start it manually to make sure everything is working as expected. To do this, open a terminal and run the following command:

```

sudo x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/rahul/.vnc/passwd -rfbport 5900 -shared

```

This will start the x11vnc server on port 5900. You can use any other VNC client to connect to the server.

Step 2: Create an Init File

To set up the auto-start feature for x11vnc, we need to create a file in the `/etc/init` directory. Open a terminal and run the following command:

```

sudo nano /etc/init/x11vnc.conf

```

Add the following content to the file:

```

description 'Start x11vnc on system boot'

exec /usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/rahul/.vnc/passwd -rfbport 5900 -shared

```

Save the file and exit.

Step 3: Set Up Auto-Start

To set up the auto-start feature for x11vnc, run the following command:

```

sudo update-rc.d x11vnc defaults

```

This will configure the system to start x11vnc on boot.

Step 4: Connect to the VNC Server

Now that we have set up the x11vnc server, let's connect to it using a VNC client. You can use RealVNC viewer or any other VNC client of your choice. Open the VNC client and enter the IP address or hostname of your Ubuntu system followed by `:5900`. For example, if your system's IP address is `192.168.1.100`, you would enter `192.168.1.100:5900`.

Step 5: Set Up Password

To connect to the VNC server using a password, we need to create a password file. Run the following command:

```

sudo x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/rahul/.vnc/passwd -rfbport 5900 -shared

```

Then, write your password to `/home/rahul/.vnc/passwd` and enter `y` to confirm.

That's it! You have successfully set up an x11vnc server on your Ubuntu 18.04 system and connected to it using a VNC client. With this setup, you can remotely access and control your machine from another device.

In this tutorial, we have shown you how to install and set up an x11vnc server on your Ubuntu 18.04 system. We hope that this tutorial has been helpful in setting up a remote support software for your Ubuntu system.
