Public bug reported:
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).
