You can disable that in your xorg.conf. I disbled middle- and right-click on my touchpad, to do that I put a file name
50-synaptics.conf in the folder
/etc/X11/xorg.conf.d/ with this content:
Code:
Section "InputClass"
Identifier "touchpad"
Driver "synaptics"
MatchDevicePath "/dev/input/event*"
MatchIsTouchpad "on"
Option "TapButton1" "1"
Option "TapButton2" "0"
Option "TapButton3" "0"
Option "VertEdgeScroll" "1"
Option "HorizEdgeScroll" "1"
Option "MinSpeed" "1.1"
Option "MaxSpeed" "1.9"
EndSection
The relevant part for clicking are the
TapButton-options, set them all to 0 and tapping should be disabled after restarting the X-server.
