Can I use Ubuntu 18.04 with Unity? [duplicate]

  • 772

I'm thinking to reinstall Ubuntu on my machine and would love to have Unity back.

I can't get used to Gnome.

What is the best way to get Unity back on the recent releases of Ubuntu?

Or is there an alternative to Unity?

The feature I miss the most is the Alt search for a menu item.

    Going back to Unity

    If you have been using Unity or GNOME in the past, you may not like the new customized GNOME desktop in Ubuntu 18.04. Ubuntu has customized GNOME so that it resembles Unity but at the end of the day, it is neither completely Unity nor completely GNOME.

    Open up a terminal window. Then run the following two commands to install Unity 7 desktop from the default software repository.

    $ sudo apt update
$ sudo apt install ubuntu-unity-desktop

    This will install a lot of packages. Once the installation is complete, restart your Ubuntu 18.04 computer.

    You can also install Unity Tweaks via the Software Center or you can use the command below to install it:

    $ sudo apt install unity-tweak-tool

    How to Install Unity Desktop on Ubuntu 18.04 LTS?

    1. Open up a terminal window. Then run the following two commands to install Unity 7 desktop from the default software repository.

      $ sudo apt update
$ sudo apt install ubuntu-unity-desktop

      This will install a lot of packages. Hit Enter to continue.

    2. During the installation, you will be asked to choose a display manager. You can choose lightdm display manager, which will give you the Unity Login screen. gdm3 is the default display manager for GNOME desktop.

      enter image description here

      Note:

      a) Use ↑or↓ to position the cursor on your choice of default desktop manager
      b) Hit Spacebar to mark your selection (Don't ignore this step).
      c) Use Tab to navigate to OK button and press Return.

    3. Once the installation is complete, restart your Ubuntu 18.04 computer.

      $ sudo shutdown -r now

    4. Now you are greeted by Unity login screen. What a warm feeling to have it back!

      Double-click Ubuntu symbol in LightDM or gear symbol in GDM to display options for desktop environments.

      enter image description here

      The default desktop environment is now Unity. You can click the Ubuntu icon to choose another desktop environment if you want to.

      enter image description here

    5. If you upgraded from Ubuntu 16.04/17.10 to Ubuntu 18.04 and the login screen was replaced with the one from GNOME desktop, you can restore Unity login screen by running the following command:

      $ sudo dpkg-reconfigure lightdm

      And here’s the good old Unity desktop.

      enter image description here

    6. Checking Unity Version

      You can use the screenfetch tool to check Unity desktop version.

      $ sudo apt install screenfetch

      enter image description here

      Now, give the following useful command to display not only version info, but also other system details:

      $ screenfetch

      enter image description here

      As you can see, we have installed Unity 7.5.0.

      You can also acquire Unity version by running the following command.

      $ unity --version

      enter image description here

      Since we installed Unity, why not install the Unity tweak tool?

      $ sudo apt install unity-tweak-tool

    7. How to Remove GNOME Desktop from Ubuntu 18.04?

      If you don’t want to keep GNOME on the list of available desktop environments, uninstall it with the following command.

      $ sudo apt remove gnome-shell

      If you now restart Ubuntu 18.04 OS, there will be no GNOME desktop in the login screen options.
