Supported Gestures

Unity has support for some system gestures, and you can try those out right away. Here's a list:

  • 3 finger pinch to maximize/restore windows
  • 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 available. However, by using Ginn configured for your window manager, you should be able to have a similar gesture experience.

Legacy Applications

Ginn is installed by default, and provides users with the ability to add gestures for applications that do not directly support gestures. Ginn supports everything from photo viewers and text editors to window managers!

The Wiki

This resource features information about multitouch support for Ubuntu, including:

  • drivers for a range of hardware
  • a gesture processing system which does the heavy lifting of gesture analysis
  • APIs for developers who want to build gestures into their apps
  • support for gesture-based window management in Unity

uTouch Overview

The Ubuntu uTouch gesture framework includes several different components and is associated with various tools and projects:

  • kernel drivers (evdev, mtdev)
  • a display server (currently only X is supported; there are future plans for Wayland)
  • Grail - the gesture recognizer
  • GEIS - platform/distro agnostic API for gestures
  • Support in toolkits (Qt, GTK)
  • Support for legacy applications (Ginn)

See the "uTouch In-Depth" section below for more information on the projects various aspects (including current work). Architectural information is available there as well.

For the full list of projects related to uTouch, be sure to see the "Projects" section on this page:
