Ubuntu 11.04 (Natty Narwhal) ships with Unity. Unity has support for some system gestures, and you can try those out right away. Here’s a list:
- 3 finger press and drag to move window
- 3 finger touch to show grab handles
- 4 finger swipe left/right to reveal launcher
- 4 finger tap to open dash
If you are running Natty with the “classic” GNOME Desktop, utouch will be installed, but since you don’t have Unity running, system gestures won’t be immediately available. However, by using Ginn configured for your window manager, you should be able to have a similar gesture experience.
