<span class="quote">> in this order. I am not entirely sure why there are 6 logs :-/</span >
last one is an empty recording, that's normal when using --autorestart.
The log ending with :23 (pinching) has some useful data, but it runs into the
issue that we bias heavily towards 2fg scrolling on touchpads that only support
2 fingers (of which this is one). Try a 4.12 kernel and see if this touchpad is
supported through rmi4 - then we'd get 5 slots and can do better gesture
detection.</pre>
