Understanding Unity 7 and Its Importance
Unity 7 is a desktop environment that made waves in the Linux community, particularly when it was used as the default desktop environment for Ubuntu from version 11.04 to 17.04. With its unique user interface, Unity sought to provide a more integrated and user-friendly experience. Although Canonical, the company behind Ubuntu, shifted its focus to other desktop environments like GNOME starting from Ubuntu 17.10, many users still prefer Unity for its distinct features, including its elegant dash, global menus, and customizable launcher.
If you are one of those users looking to install Unity 7 on Ubuntu 18.04, this guide will walk you through the process, providing all necessary details and tips to ensure a smooth installation.
Prerequisites for Installation
Before diving into the installation, ensure you meet the following prerequisites:
- Ubuntu Version: The process outlined here is specifically designed for Ubuntu 18.04 LTS. If you’re using a different version, the steps may vary.
- Internet Connection: Since Unity 7 is not included in the default Ubuntu repositories, an active internet connection is essential for downloading the required packages.
- Backup Your Data: As always when making significant changes to your system, back up important files. This will ensure you can restore your system to its original state in case anything goes wrong during the installation.
Installing Unity 7 on Ubuntu 18.04
Step 1: Update Your System
The first step in the installation process is ensuring that your package list is up to date. Open the terminal (Ctrl + Alt + T) and run the following commands:
bash
sudo apt update
sudo apt upgrade
This will fetch the latest package information and install any pending upgrades. It’s a good practice to keep your system updated before installing new software.
Step 2: Install Unity 7
To install Unity 7, you will need to add the appropriate PPA (Personal Package Archive). A PPA is a repository hosted by a user or a developer, offering packages that may not be available in the official repositories. Unity was maintained by a PPA after its official support ended.
Run the following commands:
bash
sudo add-apt-repository ppa:unity-team/stable
sudo apt update
sudo apt install unity
Add the PPA: The first command adds the Unity-stable PPA to your system, allowing you to access the latest version of Unity that has been curated by the Unity team.
Update Packages Again: The second command refreshes your package lists to include the Unity packages from the newly added PPA.
Install Unity: The final command installs Unity on your system.
Step 3: Install Additional Packages (Optional)
While Unity 7 should work well with the basic installation, there are additional packages you may want to consider for enhanced functionality. These include:
- Compiz: For window effects, it helps enhance the overall visual experience.
- Unity Tweak Tool: A handy tool for customizing Unity settings such as themes, icon sets, and launcher options.
You can install them with the following command:
bash
sudo apt install compizconfig-settings-manager unity-tweak-tool
Step 4: Selecting Unity as Your Desktop Environment
After the installation completes, log out of your session. On the login screen, look for a gear icon or a similar option that allows you to choose your desktop environment. Click on it and select “Unity” from the list of available sessions.
Now, log in! You should find yourself welcomed by the distinctive Unity interface, complete with the Unity launcher and dashboard.
Tweaking Unity for an Optimal Experience
After installation, you might want to customize Unity to fit your workflow better. The Unity Tweak Tool is a great place to start:
- Change Themes and Icons: Choose from a selection of available themes and icon packs to give your desktop a unique look.
- Customize the Launcher: You can adjust the position and size of the launcher, as well as add or remove applications from it, tailoring it to your specific needs.
- keyboard shortcuts: Familiarize yourself with keyboard shortcuts to navigate your new environment more efficiently. For example, pressing the Super key opens the dash, while Super + A displays all applications.
Troubleshooting Common Issues
While installing Unity 7 can be a straightforward process, you might encounter some issues. Here are a few common problems and their solutions:
Unity Not Starting: If Unity does not load after installing, ensure that your GPU drivers are up to date. You can also try resetting Unity settings by running the command:
bash
dconf reset -f /org/compiz/Missing Applications: If certain applications are missing from the Unity dash, you may need to reinstall or manually install them using the Ubuntu Software Center or Terminal.
performance issues: If Unity feels sluggish, consider disabling some visual effects through CompizConfig Settings Manager, or reducing the number of items in your launcher.
Advantages of Using Unity 7
While some may prefer other desktop environments, Unity 7 has several advantages that make it appealing:
- User-Friendly Interface: The design of Unity is accessible to both newcomers and experienced users, with straightforward navigation.
- Integration with Ubuntu’s Ecosystem: Unity is designed specifically for Ubuntu, ensuring that it integrates well with various system tools and services.
- Rich Customization Options: The Unity Tweak Tool allows users to customize almost every aspect of their interface easily, enhancing their user experience.
