π» What is VNC?
VNC, or Virtual Network Computing, is a popular and widely used remote desktop application that allows users to connect and control a remote computer from their own computer. VNC operates by transmitting keyboard and mouse events from the local computer to the remote computer, and transmitting screen updates from the remote computer back to the local computer. This allows users to access and control their remote computer as if they were physically present in front of it.
π VNC and Ubuntu
Ubuntu is a popular Linux-based operating system that is widely used for its ease of use and security features. VNC is a great choice for Ubuntu users who want to connect to their remote Ubuntu machine from another device, whether it’s a laptop, tablet, or smartphone.

πΉ Step-By-Step Guide to Set Up VNC Server on Ubuntu
Now that we’ve covered the basics of VNC and Ubuntu, let’s dive into the step-by-step guide on how to set up a VNC server on Ubuntu.
π§ Step 1: Install a Desktop Environment
The first step in setting up a VNC server on Ubuntu is to install a desktop environment. This will provide you with a graphical user interface (GUI) that you can use to interact with your Ubuntu machine. There are several desktop environments available for Ubuntu, but the most popular are GNOME, KDE, and Xfce.
π» GNOME
If you prefer a modern-looking and user-friendly desktop environment, GNOME is a great choice. To install GNOME on Ubuntu, open a terminal window and run the following command:
sudo apt-get install ubuntu-gnome-desktop
π» KDE
If you prefer a more customizable and feature-rich desktop environment, KDE may be the right choice for you. To install KDE on Ubuntu, open a terminal window and run the following command:
sudo apt-get install kubuntu-desktop
π» Xfce
If you prefer a lightweight and fast desktop environment, Xfce is a great choice. To install Xfce on Ubuntu, open a terminal window and run the following command:
sudo apt-get install xubuntu-desktop
π§ Step 2: Install VNC Server
Once you’ve installed a desktop environment, the next step is to install VNC server software on your Ubuntu machine. There are several VNC server options available for Ubuntu, but in this guide, we’ll be using TightVNC server.
π₯ Installing TightVNC Server
To install TightVNC server on Ubuntu, open a terminal window and run the following command:
sudo apt-get install tightvncserver
During the installation process, you’ll be prompted to set a password for the VNC server. Make sure to choose a strong password and remember it, as you’ll need it to connect to the VNC server.
π§ Step 3: Configure the VNC Server
Now that you’ve installed the VNC server software, the next step is to configure the server to use the desktop environment that you installed in Step 1.
π© Configuring the VNC Server for GNOME
If you installed the GNOME desktop environment, you’ll need to create a new VNC startup file for GNOME. To do this, open a terminal window and run the following command:
echo "gnome-session βsession=gnome-classic &" > ~/.vnc/xstartup
Once you’ve created the startup file, you’ll need to make it executable. To do this, run the following command:
chmod +x ~/.vnc/xstartup
π© Configuring the VNC Server for KDE
If you installed the KDE desktop environment, you’ll need to create a new VNC startup file for KDE. To do this, open a terminal window and run the following command:
echo "startkde &" > ~/.vnc/xstartup
Once you’ve created the startup file, you’ll need to make it executable. To do this, run the following command:
chmod +x ~/.vnc/xstartup
π© Configuring the VNC Server for Xfce
If you installed the Xfce desktop environment, you’ll need to create a new VNC startup file for Xfce. To do this, open a terminal window and run the following command:
echo "startxfce4 &" > ~/.vnc/xstartup
Once you’ve created the startup file, you’ll need to make it executable. To do this, run the following command:
chmod +x ~/.vnc/xstartup
π§ Step 4: Start the VNC Server
Now that you’ve installed and configured the VNC server software, the final step is to start the VNC server.
π Starting the VNC Server
To start the VNC server, open a terminal window and run the following command:
tightvncserver :1
This will start the VNC server on display :1. You can choose a different display number if you want to run multiple VNC servers simultaneously.
β Frequently Asked Questions (FAQs)
π Q1. How do I connect to my VNC server?
To connect to your VNC server, you’ll need a VNC viewer application on the computer or device you want to connect from. There are several VNC viewer applications available, including RealVNC, TightVNC, and UltraVNC.
π Q2. Can I use VNC with Ubuntu Server?
Yes, you can use VNC with Ubuntu Server. However, since Ubuntu Server does not have a desktop environment installed by default, you’ll need to install a desktop environment before you can use VNC. Additionally, using VNC on a server can be a security risk, so you should use caution and only allow remote access from trusted devices.
π Q3. How do I change the resolution of my VNC server?
To change the resolution of your VNC server, you’ll need to modify the VNC startup file. Open the file ~/.vnc/xstartup
and add the following line:
xrandr -s [width]x[height]
Replace [width] and [height] with the desired screen resolution, such as 1920x1080
.
π Q4. Can I use VNC over the internet?
Yes, you can use VNC over the internet. However, since VNC traffic is not encrypted by default, it is not recommended to use VNC over an unsecured internet connection. To use VNC over the internet securely, you should use a VPN or SSH tunneling.
π Q5. How do I uninstall VNC server?
To uninstall VNC server, open a terminal window and run the following command:
sudo apt-get remove tightvncserver
π Q6. What should I do if I forget my VNC server password?
If you forget your VNC server password, you can reset it by deleting the .vnc/passwd
file in your home directory. The next time you start the VNC server, you’ll be prompted to set a new password.
π Q7. How do I troubleshoot VNC connection issues?
If you’re having trouble connecting to your VNC server, there are several steps you can take to troubleshoot the issue. First, make sure that the VNC server is running and that you’ve entered the correct IP address and port number in your VNC viewer application. If you’re still having trouble, try disabling any firewalls or antivirus software that may be blocking the VNC connection. You can also try connecting to the VNC server from a different device or network to see if the issue is specific to one device or network.
