As for Unity2d it was just
  sudo apt-get install unity-2d<p>but it was removed after 12.04 if I&#x27;m not mistaken. That is why I still use 12.04 on a couple laptops. I think the time is running out for 12.04 updates, so I will need to change to something else. There is always gnome-session-flashback, I guess. Not sure if the kids will like it&#x2F;want it, as they&#x27;re used to Unity and it&#x27;s their laptops...
