Touchpad Synaptics not working in Gnome

Since a few days ago my touchpad stopped working. It works in GDM but when I log in Gnome don't work anymore.

I'm running an updated Arch 64, linux  3.4.4-3 and Gnome.

/etc/X11/xorg.conf.d/10-synaptics.conf

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
EndSection

Xorg.log output :

Re: Touchpad Synaptics not working in Gnome

I think the problem is that the touchpad is loaded twice:

20.355] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/event13)
...
20.399] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/mouse1)

If I uninstall xf86-input-synaptics the touchpad works but very snappy and does not appear touchpad tab.

Re: Touchpad Synaptics not working in Gnome

I found a temporary fix: :-)

With dconf-editor uncheck the "active" setting in /org/gnome/settings-daemon/plugins/mouse/

Now Gnome don't touch my touchpad settings
