Line 12: Line 23:
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 [[Multitouch/Ginn|Ginn]] configured for your window manager, you should be able to have a similar gesture experience. Some applications support 2 finger gestures. However, note that 2 finger gestures require [[Multitouch/TouchpadSupport|extra setup]] for touchpads in Ubuntu. Also please note that your system may not be supported out of the box, or at all.

Overview

Supported Gestures

On some systems, 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
  • 3 finger double tap -> switches to previous window

  • 3 finger tap followed by 3-fingers hold -> shows window switcher

    • drag those 3-fingers -> change selected window icon

    • release fingers -> selects window and closes switcher

  • 3 finger tap followed by 3-fingers hold -> shows window switcher

    • release fingers -> switcher will kept being shown for some seconds still

    • drag with one or three fingers -> change selected window

    • release finger(s) -> selects window and closes switcher

  • 3 finger tap followed by 3-fingers hold -> shows window switcher

    • release fingers -> switcher will kept being shown for some seconds still

    • tap on some window icon -> selects that icon and closes the switcher

  • 4 finger swipe left/right to reveal launcher (if the dock autohide is enabled)
  • 4 finger tap to open dash

Some applications support 2 finger gestures. However, note that 2 finger gestures require extra setup for touchpads in Ubuntu. Also please note that your system may not be supported out of the box, or at all.

Legacy Applications

Ginn 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! Ginn is not installed by default, and has been moved to universe repositories as of Ubuntu 12.10 (Quantal Quetzal)

About

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

Touch Overview

The Ubuntu gesture recognition 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 "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 touch/gesture recognition, be sure to see the "Projects" section on this page:
