Yes it sounds like Peter had already prototyped something like what I later suggested in https://bugs.freedesktop.org/show_bug.cgi?id=98839#c27
However I already know that's not going to fix this problem. Fixing hysteresis like that only solves the problem of the cursor moving in squares when the finger is moved in circles, at most. Whereas the X1 Carbon gen4/gen5 (and possibly X1 Yoga too) require all hysteresis to be turned _off_. This is because the hardware itself starting in gen4 has so much hysteresis built in (firmware change?) that any additional hysteresis in software makes it unusable. I can move my finger almost a centimeter before the cursor moves... -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1696929 Title: X1 Carbon gen4 and gen5 touchpads are unresponsive and laggy To manage notifications about this bug go to: https://bugs.launchpad.net/libinput/+bug/1696929/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
