Although Canonical uninstalled the Ubuntu Unity desktop at 18.04, it is still possible to use it in the new release, Ubuntu 20.04, and the company still makes it available to all who like to use it.
In this guide, we will discuss ways you can run and run the Ubuntu Unity desktop in two ways. The first way is to install it on an existing Ubuntu 20.04 system. The second method involves installing an unofficial Ubuntu Unity Remix.
Method 1 – Install the Unity desktop on 20.04 LTS
If you don’t like the new Gnome Shell desktop environment that is on Ubuntu 20.04 LTS, you will be happy to know that installing Unity is possible. To do this, start by opening a terminal window. Then, follow the step-by-step instructions below to make Unity work on your system.
Step 1: Use the Apt command below to install the Ubuntu Unity desktop environment. Add –install – suggest optionally, if you also want to install the recommended Unity desktop package.
sudo apt install ubuntu-unity-desktop --install-suggests
Or, if you don’t want to install one of the recommended packages and only what is important is needed to run Unity, run:
sudo apt-install ubuntu-unity-desktop
Step 2: During the installation of the Ubuntu Unity desktop environment, you will be asked to choose a new login screen. In the terminal UI, select the “lightdm” option.
Step 3: Close the terminal and reboot your Linux PC. Because you have chosen a new login screen, the system must be restarted.
Step 4: Find the session box, and select “Unity” as your session. Then, select your user, enter your user account password in the login box, and press Enter to enter.
After logging in, you will use Ubuntu Unity on Ubuntu 20.04 LTS! Enjoy!
Method 2 – Ubuntu Unity Remix
Being able to install the Unity desktop directly into an existing Ubuntu Linux installation is quite useful. This means that you don’t need to reform your entire system and rework it to continue. However, if you prefer to start a new one with Unity, there is Ubuntu Unity Remix.
What is Ubuntu Unity Remix? This is an unofficial Ubuntu round that follows how Ubuntu does it for the better part of a decade: with the Unity desktop as the default, rather than customized Gnome Shell. In this section, we will show you how to proceed with Unity Remix.
Step 1: Plug a USB flash drive about 2 GB (or larger) into your USB port. For best results, connect to a USB 3.0 port, because installing Ubuntu Unity Remix will be faster.
Step 2: Open this MediaFire link and download Ubuntu Unity Remix to your computer. This is a 3GB file so the download process might take a little time. Patient!
Step 3: Head to Etcher.io. Once on the website, look for the download button and click. Selecting this button will save the Etcher program to your computer. Etcher is a USB / SD flash utility, and we will need it to insert Ubuntu Unity Remix into your USB flash drive.
Step 4: After the Etcher application has finished downloading, extract it from the incoming ZIP archive, and launch it. On Linux, Etcher is AppImage. Simply extract the file and double click to run it.
If you run Etcher on a Windows or Mac computer, you must follow the instructions on the website to open it.
Step 5: Find the “Select Image” button and click with the mouse. After clicking “Select Image,” you will be presented with a browser window. Use this window to find the ISO Unity Remix Ubuntu file that you downloaded earlier.
Step 6: Click “Select Drive” and select your USB flash drive if the application has not done it for you automatically.
Step 7: Find “Flash!” button, and click with the mouse. After clicking the button, Etcher will start creating your Ubuntu Unity Remix USB installation.
Step 8: After the Etcher application has finished creating your Ubuntu Unity Remix USB, restart your computer with the USB flash drive still attached. Then, access your computer’s BIOS and configure it to boot from USB.
Step 9: Find the “Install Ubuntu” button and manage your Ubuntu installation. Keep in mind that even though Ubuntu Unity Remix uses Unity, there are still very many traditional Ubuntu installations.
After Ubuntu Unity Remix is installed, reboot your Linux PC! When your PC has finished restarting, you will be able to log in directly to the classic Ubuntu Unity desktop! Enjoy!
