In this article, we will guide you step-by-step on how to install a graphical interface on Ubuntu Server 20.04, so you can have a user-friendly experience.
Whether you are a beginner or an experienced user, you will find this guide helpful. We will explain the advantages and disadvantages of having a graphical interface, and how it can help you improve your productivity. We will also provide a table with the necessary commands and installation packages, as well as a list of FAQs.
How to Install a Graphical Interface for Ubuntu Server 20.04
Installing a graphical interface on Ubuntu Server 20.04 is a simple process that requires a few steps. Before we begin, make sure you have a stable Internet connection and have SSH access to your server.
Step 1: Updating and Upgrading
The first step is to update and upgrade your Ubuntu Server. This ensures that your system has the latest security patches and bug fixes. To do this, run the following command:
sudo apt update |
Updates the package list |
sudo apt upgrade |
Upgrades installed packages |
Once the update and upgrade process is complete, reboot your server using the command:
| sudo reboot | Reboots the server |
After the server is rebooted, log in to your server via SSH.
Step 2: Install a Desktop Environment
The next step is to install a desktop environment. There are several desktop environments available for Ubuntu Server, including GNOME, KDE, Xfce, Mate, and LXQt. In this example, we will be using the GNOME desktop environment.
To install GNOME, run the following command:
| sudo apt install -y ubuntu-desktop | Installs the GNOME desktop environment |
The “-y” flag tells apt to assume “yes” when prompted to install packages.
Step 3: Install a VNC Server
In order to connect to the desktop environment, we need to install a VNC server. A VNC server allows remote access to the desktop environment using a VNC client. In this example, we will be using TigerVNC.
To install TigerVNC, run the following command:
| sudo apt install -y tigervnc-standalone-server | Installs TigerVNC |
Step 4: Configure the VNC Server
Once TigerVNC is installed, we need to configure it to allow remote access. To do this, create a password file using the following command:
| vncpasswd | Creates a password file |
You will be prompted to enter a password. This password will be used to connect to the VNC server.
Next, create a systemd service file for TigerVNC using the following command:
| sudo nano /etc/systemd/system/vncserver@.service | Creates a systemd service file |
Paste the following configuration into the file:
| [Unit]Description=VNC server startup script for Ubuntu 20.04After=syslog.target network.target[Service]Type=forkingUser=usernameWorkingDirectory=/home/usernamePIDFile=/home/username/.vnc/%H%i.pidExecStartPre=/usr/bin/vncserver -kill :%i > /dev/null 2>&1ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280×800 -localhost :%iExecStop=/usr/bin/vncserver -kill :%i[Install]WantedBy=multi-user.target | Configures the VNC server |
Replace “username” with your desired username.
Save and close the file.
Next, reload systemd using the following command:
| sudo systemctl daemon-reload | Reloads systemd |
Enable and start the VNC server using the following commands:
sudo systemctl enable vncserver@1.service |
Enables the VNC server |
sudo systemctl start vncserver@1.service |
Starts the VNC server |
The number “1” after “vncserver@” specifies the display number.
Step 5: Connect to the VNC Server
Now that the VNC server is running, we can connect to it using a VNC client. There are several VNC clients available, including RealVNC, TightVNC, and TigerVNC. In this example, we will be using TigerVNC.
To connect to the VNC server, download and install TigerVNC from the official website. Once installed, open TigerVNC and enter your server’s IP address and display number (in this example, “1”) in the “Remote Host” field.
Click “Connect,” and enter the password you created earlier. You should now be connected to the GNOME desktop environment on your Ubuntu Server.
