https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #17 from Daniel van Vugt --- I think the way forward here is: 1. Use fuzz as the hysteresis threshold(s). 2. Modify hysteresis to be omnidirectional (test if raw (dx,dy) is within the ellipse defined

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #16 from Daniel van Vugt --- When I say "wobbles", I mean the problems with 'wip/hysteresis-wobbles' are bigger than the problems with 1.10 that I originally called "jitter". -- You are receiving

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #15 from Daniel van Vugt --- Tested 'wip/hysteresis-wobbles' on Yoga 11S. It seems more broken than any other branch so far. The cursor actually wobbles in directions that the finger isn't going in.

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #10 from Daniel van Vugt --- Sounds like a plan: 1. Start using fuzz if available. 2. Never disable hysteresis; and 3. Submit proper measurements and fuzz tweaks per-model. And maybe in parallel:

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #9 from Peter Hutterer --- it's already doable, the EV_ABS lines in 60-evdev.hwdb support fuzz and flat as well (order is x:y:resolution:fuzz:flat). But before we do that we need a tool to measure what the

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #8 from Daniel van Vugt --- The wobble is gone because hysteresis is always enabled (I hardcoded it to enabled). That's not a change introduced by the patch though. Moving in squares (when the finger

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #7 from Peter Hutterer --- 'moves in squares' when you actually move the cursor, right? Does it wobble? 1) fwiw, a bug link is not always a signal that the bug is fixed, but rather a reference to some

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #6 from Daniel van Vugt --- Confirmed on two machines (Yoga 11S and X1 Carbon gen 5) that using fuzz is a better idea than resolution/2. Just still not as good as completely disabling hysteresis (the

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #4 from Daniel van Vugt --- Sounds like a good idea, but also like something I can't test unless I add some hacks to stop hysteresis from quickly turning off, right? Also, even if that worked the

https://bugs.freedesktop.org/show_bug.cgi?id=105108 --- Comment #3 from Peter Hutterer --- it's unrelated, it just changes how the hysteresis behaves when it's enabled but it doesn't affect when/how it is enabled/disabled. ideally, it should make the touchpad more
