#  Set up the Synaptics TouchPad for two-finger scroll
#  and button presses, but not mouse pointer motion.
#  (that's what the IBM TrackPoint is for.)
#
#  This works on a Lenovo ThinkPad T440s.
#
#  Based on discussion on Havoc Pennington's blog:
#    http://blog.ometer.com/2013/12/04/fedora-20-beta-on-thinkpad-t440s-report/
#
#  Run with the argument: install
#  to set this up to run at start of each desktop session.
