Unsolving Ubuntu on Macbook Issue: App Switching by Two Finger Scrolling

I think this was a problem or bug caused by Ubuntu installed on Macbook. However this is a new feature of Ubuntu supporting multitouch devices. Occasionally, when I placed my two finger (I didn't realize the third) on Mac touchpad, the application switcher appears and select a window app from switcher. It was annoying me at the first, but when I know this is a new feature, I realize my fault (my third finger erratic touch the pad), and get benefit of it.

App switcher appears erratic on Ubuntu on Mac

Yes, this was three fingers tap followed by hold to switch between app windows, not two fingers. The explanation is given below. Yatta! Canonical and Ubuntu are struggling hard to make multitouch devices working perfectly.

The best solution is to adapt it, not to disable it. By time it will be improved and here is the current 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
