Here is the sequence after lifting one of the fingers:

And here is the sequence after lifting the remaining finger:

If the driver reports one of BTN_TOUCH or ABS_PRESSURE in addition to the

ABS_MT events, the last SYN_MT_REPORT event may be omitted. Otherwise, the

last SYN_REPORT will be dropped by the input core, resulting in no

zero-finger event reaching userland.

[3] The multi-touch X driver is currently in the prototyping stage. At the

time of writing (April 2009), the MT protocol is not yet merged, and the

prototype implements finger matching, basic mouse support and two-finger

scrolling. The project aims at improving the quality of current multi-touch

functionality available in the Synaptics X driver, and in addition

implement more advanced gestures.
