Description Peter Lewis 2016-03-04 23:56:52 UTC 
Hi,

The KCM touchpad module caps certain values, e.g. 20.0 for vertical and horizontal scroll distance, and 20 for maximum finger movement.

For me, I need touchpad values that are much higher. This works well for me:

synclient VertScrollDelta=100 HorizScrollDelta=100 MaxTapMove=50

As it stands, the defaults and also all ranges that I can set within the UI lead to far too sensitive touchpad use (e.g. such that scrolling is impossibly too sensitive).

The caps should be removed, and the default values should also be more sensible (higher).


Reproducible: Always

Okay, I just found this discussion:

I don't think there is any issue with the driver detecting my touchpad's resolution correctly though...
