-commit d5ff9d8b0b186cf39695df84a10984eac559b746
+ Turn down the default sensitivity for unibody MacBook touchpads
+
+ The touchpads are too sensitive by default. A touch is activated when a
+ finger hovers a millimeter off the device. This change turns down the
+ default sensitivity so that accidental touchpad interactions are
+ lessened and pointer interaction accuracy is increased.

+ Initially, treat them the same as MODEL_APPLETOUCH devices, as that is

Title:
Ubuntu 13.10, wrong settings for Apple (mouse) touchpad in Macbook 4,1
Status in “xserver-xorg-input-synaptics” package in Ubuntu:
Confirmed
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
mouse.
2) Having enabled Two-finger tap for right click, using vertical
scrolling with two fingers often ends up in a right click.
Fixes:
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"
EndSection
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).
