After reading Kai's posting I solved the problem permanently by adding the following lines to /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf
Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "SHMConfig" "on" Option "TapButton1" "1" Option "TapButton2" "2" Option "TapButton3" "3" Option "VertTwoFingerScroll" "1" Option "TapAndDragGesture" "1" Option "SingleTapTimeout" "320" Option "FastTaps" "1" EndSection
