How do I disable the touchpad on a Lenovo V570 in Ubuntu 11.10?

[brian71]

I have a Lenovo V570. I am running Ubuntu 11.10.

Until a few days ago, I could disable my touchpad with the following command:

xinput set-prop 12 "Device Enabled" 0

But now when I try that command, my system acts like something is holding down the Return key, and I have to restart the system to make it stop (e.g., constant scrolling in shell or gedit; hovering the cursor over an icon or menu using the mouse instantly activates it).

Here's what I get when I do "xinput list":

⎡ Virtual core pointer          id=2     [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer  id=4     [slave pointer (2)]
⎜ ↳ Logitech USB Optical Mouse  id=9     [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad  id=12    [slave pointer (2)]
⎣ Virtual core keyboard         id=3     [master keyboard (2)]
↳ Virtual core XTEST keyboard   id=5     [slave keyboard (3)]
↳ Power Button                  id=6     [slave keyboard (3)]
↳ Video Bus                     id=7     [slave keyboard (3)]
↳ Sleep Button                  id=8     [slave keyboard (3)]
↳ Lenovo EasyCamera             id=10    [slave keyboard (3)]
↳ AT Translated Set 2 keyboard  id=11    [slave keyboard (3)]
↳ Ideapad extra buttons         id=13    [slave keyboard (3)]

I'm guessing that this has something to do with one of the updates I installed the day or two prior to this problem cropping up.

Any ideas would be appreciated!
