Comment 5 for bug 966619

I have a Lenovo Thinkpad T440s, which has a ClickPad.
It should support at least 3 finger touches:

xinput --list-props 12 | grep Capabilities
        Synaptics Capabilities (317): 1, 0, 0, 1, 1, 1, 1

but geistest and grail-test tell me:

geis: attr "device touches" = 2
grail: Maximum touches: 2

I disabled the 2 and 3 finger handling in synaptics and then, touchegg recognizes 2 finger gestures.
But I'm not able to use 3 or more finger gestures :(
I'm using KDE, but output and behaviour is the same in fluxbox.

I'm not sure if this device is a real Multi-touch device or not, so maybe it's a different bug?
