I have a Magic Trackpad, it's configured as described here. The following works:

  • 1 finger Tap = Leftclick
  • 2 finger Tap = Rightclick
  • 3 finger Tap = Middleclick
  • 2 finger Drag = Scrolling

But out of curiosity, I'd like to play with PyMT, which comes with a nice multitouch demo (Details: https://wiki.ubuntu.com/Multitouch/PyMT).

When starting it with "sudo python -m pymt.tools.demo", the PyMT-Window opens but doesn't register/display any multitouching. Actually, it doesn't display anything but a blank window where the touches show show up. I was expecting something like in this Screenshot.

Any ideas where I went wrong or what I didn't correctly understand? :-)

Since you've configured your MT to use the synaptics driver, it's working in a kind of "touchpad emulation" mode. My understanding is that the true multitouch and gesture functionality requires the evdev driver, which unfortunately doesn't provide the same basic pointing functions (two-finger scrolling, two and three-finger taps) with the MT at the moment. So for this release, true multitouch gestures and basic pointing functions are mutually exclusive, and we're resorting to synaptics as a temporary measure until evdev catches up.

You can follow multitouch-related happenings by joining the multi-touch-dev mailing list, or visiting the #ubuntu-touch channel on Freenode.

Please see this to get help and see other resources about MultiTouch in Ubuntu: https://wiki.ubuntu.com/Multitouch#Community%20Help

There is a detailed guide there for using the Apple MT in Ubuntu, including the PyMT demo wiki - which I have since updated.
