Bug#362853: I had the same problem

[Miriam Ruiz <little_miry@yahoo.es>]

I had the same problem. I have a "AlpsPS/2 ALPS DualPoint TouchPad" ( cat
/proc/bus/input/devices )

According to: http://gentoo-wiki.com/HARDWARE_Synaptics_Touchpad , the
"InoutDevice" section should be very different for Synaptic users as opposed
to ALPS users.

I solved it by replacing, in /etc/X11/xorg.conf :

Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"		"/dev/psaux"
	Option		"Protocol"		"auto-dev"
	Option		"HorizScrollDelta"	"0"
EndSection

	Option "CircularScrolling" "1"

EndSection

The activation of SHMConfig makes it possible to use the synclient command:
synclient -l
