<pre>Indeed, I see only a few motion events on my T440 where I can hold the finger
still and get few events. The hysteresis was originally added to the synaptics
driver because just holding down a finger on a device would wobble the cursor
by a couple of pixels, looks like recent hardware has that in check. I'll have
to test a few older devices again.
Which means that rather than having an option to disable this, we can just
enable it on a per-device basis where it is needed.
Note that we do subpixel motion from libinput though, so it's not enough to
just look at the cursor. Run sudo libinput-debug-events with the hysteresis
disabled, do you see motion events there?</pre>
