<pre>the resolution itself is also used for determining the real touchpad size and a
bunch of other things hang off that. So we can't really half the resolution
without breaking other bits. and the hysteresis also has a moving center which
makes some motion a bit more reliable.
what you're looking for is potentially adjusting the fuzz value which is
something we could do instead of enabling the hysteresis. I never thought of it
that way. But this is where it gets a bit blurry. All the other special device
models adjust for size and actual resolution which are definitive hardware
properties. The fuzz value is more implementation-dependent as some other
implementation may not care about fuzz. so I think I'm more comfortable having
this in libinput.
Also note that the wobbly touchpad tag is named like this for a reason. right
now it only enables the hysteresis but if we find a better way to deal with
this we may change this at any time in the future.
Thanks for testing, patch is on the list
