6. Move The Unity Launcher
The Unity launcher is locked to the left-hand side of your screen by default. If you would prefer to move the Unity launcher to the bottom of the screen you can.
Keep in mind that the Unity desktop and its features were designed with the left-hand side of the screen in mind, so some features may look wonky.
Simple open a new Terminal window (Ctrl + Alt + T) and enter the following command.
gsettings set com.canonical.Unity.Launcher launcher-position Bottom
Don’t like the command line? You can also adjust this setting in Unity Tweak Tool > Unity > Launcher > Position).
