Hi Vince,

I'm answering from the bug report so everybody can see my results in a Vostro 3360.

You're right about two-finger scrolling, it seems to work by default ("synclient -l" gets configured with FingerLow=12/FingerHigh=15). I figured out that it doesn't work _perfectly_ (I'm still getting frequent pointer movements instead of scrolling up/down) if I use the middle finger + ring finger. It works much better if I use the index finger + middle finger nail instead (YMMV, of course).

On the other hand, the edge scrolling, even setting FingerLow=5 FingerHigh=6 does not work, or does it in very seldom cases.

Thank you!
