--- Comment #9 from Peter Hutterer <peter.hutterer at who-t.net> ---
ok, that's jitter so we talk about the same thing. The problem is that the
recordings didn't reproduce this in a useful manner, ideally you could provide
me with an evemu-recording that reproduces the jitter on a single-finger
movement.

Anyway, save this as /etc/udev/hwdb.d/90-libinput-yoga.hwdb, then run sudo
udevadm hwdb --update, then reboot.

libinput:name:*SynPS/2 Synaptics TouchPad*:dmi:*svnLENOVO*pvrLenovoYoga213:*
 LIBINPUT_MODEL_WOBBLY_TOUCHPAD=1

Note the space before the LIBINPUT_.. tag
When successfully applied, udevadm info /sys/class/input/eventX should show the
tag applied. If it doesn't show up, make sure I didn't add a typo.
