I'd like to use some of the Unity multitouch features. I know my touchpad supports 2 finger gestures since it scrolls when I 2 finger drag on the touchpad.
How can I test to see if my touchpad supports three and four finger gestures? All the hardware documentation just mentions that the touchpad is multitouch and doesn't specify how many fingers it support. It's a Thinkpad X120e and this is what dmesg says:
[ 14.821482] Synaptics Touchpad, model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xd000b3/0x340000/0xa0400
[ 14.821498] serio: Synaptics pass-through port at isa0060/serio4/input0
[ 14.864676] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio4/input/input7

As an update to htorque's answer, you must now use
geis-tools
instead ofutouch-geis-tools
(> 12.04). So run the following set of commands:In the new window, go under
Device
<device_id>
Added:
<device_name>
(Probably the last option) and checkdevice touches: <finger_number>
. finger_number will tell you the number of multi-touch fingers your touchpad supports.
