n April 2011 Shuttleworth announced that Ubuntu 11.10 would not include the classic GNOME desktop as a fall back to Unity, unlike Ubuntu 11.04 Natty Narwhal. Instead, 11.10 included a 2D version of Unity as a fallback for computers that lacked the hardware resources for the Compiz-based 3D version. However, the classic GNOME desktop remained available in Ubuntu 11.10 through a package in the Ubuntu repositories.[131] Shuttleworth also confirmed that Unity in Ubuntu 11.10 would run as a shell for GNOME 3 on top of GNOME 3 libraries, unlike in Ubuntu 11.04 where it ran as a shell for GNOME 2. Moreover, users were able to install the entire GNOME 3 stack along with GNOME Shell directly from the Ubuntu repositories; to be presented with a "GNOME 3 desktop" choice at login.[132] During the development cycle there were many changes to Unity, including the placement of the Ubuntu button on the Launcher instead of on the Panel, the autohiding of the window controls (and the global menu) of maximized windows, the introduction of more transparency into the Dash (and the Panel when the Dash was opened) and the introduction of window controls for the Dash.[133]
