This bug affects me aswell. The touchpad works in lightgdm then it stops working when Unity loads. Worked well with 11.04. Touchpad is well recognized by kernel (ETPS/2 Elantech Touchpad appears in xinput --list), but is desactivated.
This is what happens when I try to use xinput set-int-prop 13 "Device Enabled" 8 1 (output of watch-props): Device Enabled (144) (558): 1 Property 'Device Enabled' changed.
