[Bug 1271281]


yeah, it's an issue that affects any clickpad, and it's caused by
synaptics still primarily handling touchpads as single-touch devices. a
few additions allowed for some MT stuff, but the driver needs
significant changes to be true multitouch capable - and that's out of

Changing bug title to drop the device specifics.

  05ac:0252 Rev 02.19 bcm5974 [MacBookPro9,2] Unable to move mouse via
  touchpad when finger resting on touchpad click button

Status in xf86-input-synaptics:
Status in “xserver-xorg-input-synaptics” package in Ubuntu:

Bug description:
  1) lsb_release -rd
  Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04

  2) apt-cache policy xserver-xorg-input-synaptics
    Installed: 1.7.1-0ubuntu1
    Candidate: 1.7.1-0ubuntu1
    Version table:
   *** 1.7.1-0ubuntu1 0
          500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
          100 /var/lib/dpkg/status

  3) What is expected to happen by default is when one rests their
  finger on the touchpad click points, and with the other hand attempts
  to move the cursor via the touchpad, it would move.

  4) What happens instead is the cursor does not move.

  WORKAROUND: Remove finger from click point first, then cursor moves
  via touchpad.
