Yesterday I was just looking for a solution to this same problem on my
notebook.

I have found out that synaptics now defaults to dual finger scrolling
(see the man mage), and tap to click is off by default. I have added the
following in my configuration file:

Section "InputDevice"
	Identifier	"Touchpad"
	Driver		"synaptics"
	Option		"Device" "/dev/input/mice"
	Option		"Protocol" "auto-dev"
	Option		"Emulate3Buttons" "yes"
	Option		"SendCoreEvents" "true"
	Option		"SHMConfig" "true"
	Option		"TapButton1" "1"       # Left button
	#Option		"TapButton2" "2"       # Right button
	#Option		"TapButton3" "3"       # Middle button
EndSection
