--- Comment #4 from Peter Hutterer <peter.hutterer at who-t.net> ---
synaptics and libinput use exactly the same events as input. the switch between
RMI4 and PS/2 is largely because different series of devices have different
firmware bugs.

the cause of the issue is, most likely, that the firmware filters out the
events at low speeds. synaptics has a slower acceleration by default, requiring
more/faster movement, and is thus less likely to trigger that bug.

Bug 101139 is probably of interest here, it contains a branch for different
touchpad acceleration in libinput.
