--- Comment #9 from L Holland <lucian+freedesktop at symposion.co.uk> ---
It's certainly possible that the patch helped somewhat; it's just really hard
to distinguish subjectively between the level of "jumpiness" between restarts.
All I can say is that as things stand it is still challenging to do finer work
with the trackpad.

Maybe there's a problem with what I've done, however. You say that one of the
categories of jump in the latest recording ought to be fixed by the patch; but
the recording was made *after* I applied the hwdb changes, so this jump
shouldn't be showing up at all now.... but as you can see from the udevadm info
output, that variable does appear to be set, so I'm confused. Have I
misunderstood here or is there some other way to check that the updated
behaviour really is being used?
