changing window and trying to scroll one line of text
Dear libinput devs,
since Debian testing uses libinput by default the touchpad on my Lenovo
ThinkPad L430 is very hard to use. It is super sensitive. I had another person
use the touchpad for some minutes and it resulted in a pained hand. If you want
to scroll one line of text e.g. in your web browser you have to roll your
finger tips with a resolution of 1/2 or 1/3 of a millimeter. And you have to
keep them there, or you scroll a bit back when lifting the fingers. And when
scrolling in some applications (e.g. gnome terminal 3.20) holding the touchpad
will give you a jittery scrolling (10 - 20 pix up and down).
I heard the approach of libinput is to have a great default configuration
upstream instead of configurability. I like that. So here i am. Wanting to make
sure the touchpad is usable for 90% of the people. Although your bug reporting
guide only talks about bugs in the traditional sense of misbehaviour i
completed all the steps and here my results:
----
Version: 1.3.0-2 (Debian Testing/Stretch)

Attached is the evemu file. I changed the window and tried to scroll one line
only. I hope it helps you to understand how finicky the touchpad is.</pre>
