1. Installing VNC Server on Ubuntu

Step 1: Connect to your Ubuntu server

Ensure you have SSH access to your Ubuntu server. You can use tools like PuTTY (for Windows) or Terminal (for macOS/Linux) to connect remotely.

Step 2: Update package list

Run the following commands to update the package list:

sudo apt update
sudo apt upgrade

Step 3: Install a desktop environment (if not already installed)

If your server doesn’t have a desktop environment, install one. XFCE is a lightweight option:

sudo apt install xfce4 xfce4-goodies

Step 4: Install a VNC server

Install a VNC server like TightVNC:

sudo apt install tightvncserver

Step 5: Start the VNC server

Run the VNC server to set up a password and start a session:

tightvncserver

It will prompt you to set a password for VNC access. After setting the password, it will start a VNC server session.

Step 6: Configure VNC server

Stop the VNC server to configure it:

tightvncserver -kill :1

Edit the configuration file:

nano ~/.vnc/xstartup

Add the following lines at the end of the file:

#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &

Step 7: Restart the VNC server

tightvncserver

2. Accessing Ubuntu Server from a VNC Client

To access the Ubuntu server from your local machine:

1. Download a VNC client (e.g., RealVNC, TightVNC, TigerVNC) on your local computer. https://www.tightvnc.com/download.php

2. Open the VNC client and enter the server's IP address followed by the VNC server port (default is :1).

3. Enter the password you set earlier.
