As you may well know, Ubuntu comes with Unity Desktop by default. Now, if Unity is not what you’re used to, you can still switch your desktop session to the Gnome Desktop easily by running just one command.
Step 1 : To get started, press Ctrl + Alt + T on your keyboard to open Terminal. When it opens, run the commands below to enable Gnome
sudo apt-get upgrade sudo apt-get install gnome-session-fallback
