[Wayland-bugs] [Bug 98839] Somehow conditionalize hysteresis (hardware black/whitelist, device property introspection, user-exposed setting, etc)

--- Comment #44 from Nate Graham <pointedstick at zoho.com> ---
The GUI to control Synaptics in KDE Plasma's system settings exposes a slider
that does just that: it lets the user determine the small movement smoothing
threshold in millimeters. I know  I know, "random number generator" and all
that--but such a slider is basically what we're are asking for here. Being able
to set a smoothing threshold that goes from 0mm to, say, 5mm, in increments of
0.1mm, seems like it would solve this problem.

There is some urgency here because technological progress being what it is, the
percentage of laptops with really low-quality touchpads of the sort that
hysteresis improves is likely to drop over time. Without the ability to
configure or turn off software hysteresis, libinput will become almost unusable
for a larger and larger share of our users' hardware.

And it really is almost unusable for touchpads that don't need libinput's
additional hysteresis: it destroys slow-speed precision for those touchpads,
and using it is a truly maddening experience. An unchangeable default that
renders the touchpad frustrating for those with decent quality hardware isn't
likely to generate a neverending stream of appreciation for libinput in the
Linux community. :)
