The good thing is the Workspace feature is only disabled and not removed from the system. With this simple trick, you can easily re-enable the Workspace feature in Ubuntu 14.10, and also earlier versions of Ubuntu.

  1. In Ubuntu 14.10, go to “System Settings”.
  2. Go to the “Appearance” section.
  3. Under the “Behavior” tab you can find the option “Enable workspaces.” Select the option.

That’s it. You should now see the Workspace icon in the Unity launcher bar. In addition, you can also make use of the keyboard shortcut “Ctrl + Alt + arrow key” to move between the workspaces.
