  Ubuntu 13.10, wrong settings for Apple (mouse) touchpad in Macbook 4,1

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

Bug description:
  The default settings for the touchpad of a macbook 4,1 in Ubuntu 13.10
  render an awkward mouse behaviour that is found during and after
  installation. The following issues are found:

  1) Moving the cursor shows an intermittent behaviour because the
  parameters for FingerLow and FingerHigh are way too high, hence
  affecting the sensitivity and requiring more pressure to move the

  2) Having enabled Two-finger tap for right click, using  vertical
  scrolling with two fingers often ends up in a right click.


  I have permanently fixed the settings by editing the first Section
  block in file "/usr/share/X11/xorg.conf.d/50-synaptics.conf"

  Section "InputClass"
          Identifier "touchpad catchall"
          Driver "synaptics"
          MatchIsTouchpad "on"
  # This option is recommend on all Linux systems using evdev, but cannot be
  # enabled by default. See the following link for details:
  # http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
        MatchDevicePath "/dev/input/event*"
             Option "FingerLow" "30"
             Option "FingerHigh" "40"
             Option "MaxTapMove" "25"

  The added parts are:
             Option "FingerLow" "30"
             Option "FingerHigh" "40"
             Option "MaxTapMove" "25"

  where FingerLow and FingerHigh fix issue (1), and MaxTapMove fixes
  issue (2).
