it was ok for some days after the installation, and then it stop to be 
controllod by ubuntu software: I can use it but I cannot modify 
preferences: there is no tab "Touchpad" in System -> Preferences -> 
Mouse. I've removed nad then re-installed gsynaptics but with no 
results; I've tried also GPointing but nothing.  Anyone can help me?
