Comment 12 for bug 838105

Concerning Ehsanul Hannan's question:

     Any ideas how I can activate the multi-touch features like pinch zoom, momentum, ChiralScroll etc?

Have a look at the synaptics manpage by typing "man synaptics" and you'll get a list of supported features
and how to enable them.

E.g. to enable chiral scrolling you could enter the following command in a terminal under X:

  xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Circular Scrolling Trigger" 8 0

Just google for similar commands and you'll get an idea of how to enable/disable different features.
I disabled the edge scrolling and use two finger scrolling, two finger tapping for middle mouse button
emulation (so I can open links in a different tab with the browser easily), but this is all a matter of
personal taste.
