What is 'Ubuntu Unity' (for the Desktop)?

I haven't used Ubuntu since like version 9 or something. Now that I just downloaded and installed v12, I want to know what all the talk about "Unity 3D" is about? Am I right to assume that Ubuntu now uses the Unity 3D? And am I right to assume that Unity is just the theming scheme of Ubuntu? (Pretty much like Aero on Windows 7?)

"Unity" is Ubuntu's default desktop environment, like the old Gnome and KDE you may remember. In a very simplistic way, sure, it's a "theming scheme" like Aero.

Am I right to assume that Ubuntu now uses the Unity 3D?

No, Ubuntu's Unity has nothing to do with the Unity 3D gaming engine.

  • Just Unity usually refers to Unity 3D, which is prettier but requires a reasonably modern video card; Unity 2D is the version for low-end computers.

  • If you prefer the "classic" pre-9.10 Ubuntu experience, try installing the gnome-session-fallback, which will show up on your login screen as Gnome-Classic

  • For lots more info on Unity and pretty pictures, see http://unity.ubuntu.com/about/
