My touchpad uses the synaptics driver.
This is the relevant bit in my
/etc/X11/xorg.conf
Code:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizScrollDelta" "0"
Option "MaxTapTime" "0"
EndSection
The
red lines have disabled horizontal scrolling and tap-to-click.
So edit your
xorg.conf (as root, or you cannot save the changes and make a backup first!) and add
Option "MaxTapTime" "0"
You need to restart X for the change to happen (Just logout, then back in to do this)
