Unity has no control over the kernel driver or the x.org driver used to
support various hardware.  If you choose to modify your system and
configure it to use drives that do not support multi-touch input
properly, you will get improper support for multi-touch in your system,
but that is not a bug in individual applications like Unity.

The Wacom driver does not support the XInput 2.2 multi-touch protocol.
Multi-touch on Ubuntu requires multi-touch support in the drivers.

Title:
  Make three- and four-finger gestures on touch screen also work in
  Wacom mode

Status in “unity” package in Ubuntu:
  Invalid

Bug description:
  I have a Lenovo Thinkpad Twist (convertible with touch screen) running
  Saucy with standard Unity desktop. With all in its default
  configuration, tapping on a window with three fingers added some
  resize buttons to it, dragging with three fingers dragged the window,
  and tapping anywhere with four fingers opened Dash.

  All this does not work any more when running the touch screen with
  Wacom driver to enable screen rotation (bug 1216065) and a right-click
  emulation by holding a finger on the place where the right click
  should happen and then tapping anywhere else with a second finger.

  It would be great to make the standard Unity gestures
  (https://wiki.ubuntu.com/Multitouch) also work under the Wacom driver.

  I enabled the wacom mode by adding "|Atmel" to the "MatchProduct" line
  in the "InputClass" section with Identifier "Wacom class" in
  /etc/X11/xorg.conf.d/50-wacom.conf (copy of file
  /usr/share/X11/xorg.conf.d/50-wacom.conf).
