MacBook vertical scroll sensitivity

[moodyMoose]

Hi there

I’m using my MacBook Pro 2015 A1502 with Tumbleweed and GNOME.
I’ve noticed that the vertical scroll sensitivity of the trackpad is very heigh.

In the settings of GNOME / Tweaks there is just a option to customize the sensitivity of the trackpad in general, but not the scroll sensitivity.

After a short look up in this forum I’ve found only a solution for synaptic trackpads:

Synaptic vertical scroll suddenly very sensitive

I’ve just updated to the latest Tumbleweed (applying 20160228 to 20160305). I’m getting an annoying problem where the vertical scroll setting is now very sensitive, where a small movement of the finger on the RHS edge produces a huge movement on screen. I found that setting the “Scroll Distance, Vertical” to its maximum (10mm) slows it down a little, but it is still a lot faster than I would prefer - the previous setting for this value was 1.2mm, so something is very wrong! Is anyone else seein…

Is there also a solution for the Apple MacBook trackpad available?
I would like to reduce the sensitivity.

Thanks in advance.

To start with, could you please share the output of
sudo libinput list-devices
Then we can see what is possible with libinput.

I don’t own such hardware to test with, but hopefully you’ll be able to try it and see whether it helps to provide an acceptable means to adjust vertical edge scrolling speed.
