🔧 Introduction
Greetings, fellow tech enthusiasts! If you’re reading this article, chances are you’re either new to Ubuntu or are looking for ways to improve your VNC server configuration. Fear not, for we’ve got you covered! In this comprehensive guide, we’ll be delving deep into the nitty-gritty of configuring VNC server on Ubuntu and explore the various advantages and disadvantages of this popular remote desktop protocol.
Before we dive into the specifics, let’s take a brief look at what VNC is and how it works. VNC, short for Virtual Network Computing, is a graphical desktop sharing system that allows you to access a remote computer over a network connection. With VNC, you can control the desktop environment of another computer as if you were sitting right in front of it. VNC is a powerful tool that has a variety of use cases, from remote support and administration to accessing your home or office computer from outside.
Now that we’ve covered the basics, let’s get started on configuring VNC server on Ubuntu.
🔧 Configuring VNC Server on Ubuntu: Step-by-Step Guide
Step 1: Install VNC Server on Ubuntu
The first step in configuring VNC server on Ubuntu is to install the VNC server software. There are several VNC server software packages available for Ubuntu, but the most popular is TigerVNC. To install TigerVNC, open a terminal window and run the following command:
sudo apt-get install tigervnc-standalone-server
Once the installation is complete, you can start the VNC server using the following command:
vncserver
This will start a new VNC server session, which you can connect to from any VNC client.
Step 2: Configure VNC Server on Ubuntu
By default, VNC server starts a new session on display :1. To configure the VNC server, you need to create a configuration file in /etc/vncserver/ directory. To do this, create a new file called xstartup in /etc/vncserver/ directory using the following command:
sudo nano /etc/vncserver/xstartup
In this file, you need to specify the environment variables and commands that will be used to start your desktop environment. Here’s a sample configuration file for Ubuntu:
#!/bin/shexport XKL_XMODMAP_DISABLE=1unset SESSION_MANAGERunset DBUS_SESSION_BUS_ADDRESS[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup[ -r /etc/x11/xinit/xinitrc ] && exec /etc/x11/xinit/xinitrc[ -r $HOME/.xinitrc ] && exec $HOME/.xinitrcexec /bin/bash
Save the file and exit the editor. Now, you need to make this file executable using the following command:
sudo chmod +x /etc/vncserver/xstartup
Next, you need to create a new VNC server configuration file in the /etc/systemd/system/ directory using the following command:
sudo nano /etc/systemd/system/vncserver@.service
Add the following lines to this file:
[Unit]Description=Start TightVNC server at startupAfter=syslog.target network.target[Service]Type=forkingUser=usernameGroup=usernameWorkingDirectory=/home/usernameExecStart=/usr/bin/vncserver -autokill -geometry 1920×1080 -depth 24 %iExecStop=/usr/bin/vncserver -kill %i[Install]WantedBy=multi-user.target
Replace username with your Ubuntu username. Save the file and exit the editor. Now, you need to reload the systemd daemon and start the VNC server service using the following commands:
sudo systemctl daemon-reloadsudo systemctl start vncserver@1.service
Your VNC server should now be up and running.
Step 3: Connect to VNC Server from a Remote Client
Now that you’ve configured VNC server on Ubuntu, you need to connect to it from a remote client. To do this, you need to install a VNC client on your local machine. There are several VNC clients available, but RealVNC Viewer is one of the most popular and reliable options.
To install RealVNC Viewer, download it from the official website and install it on your local machine. Once installed, open RealVNC Viewer and enter the IP address of your Ubuntu machine and the display number (in this case, :1) in the address bar. Click the Connect button, and you should be able to connect to your Ubuntu machine’s desktop environment.
