Adding WheelScrollLines=6 is not helpful.

But
As this quoted KDE bug below mentions, libinput is the culprit.
Commenting out the first section (MatchIsPointer "on") in /etc/X11/xorg.conf.d/40-libinput.conf disabled libinput support for the mouse and then automatically "evdev" is used.

The Mouse settings in KDE are now more featureful.

Curious, my 15.2 40-libinput.conf pointer section reads:

Code:

# Match on all types of devices but joysticks
Section "InputClass"
        Identifier "libinput pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput" EndSection

It is not commented out in the other sections too (keyboard, touchpad, etc.

And changing the WheelScrollLines as in my previous post works here.

I figured that libinput is the culprit on 15.2 for the missing advancded mouse KDE system settings.
So i removed xf86-input-libinput and voila ..... more mouse settings are visible in KDE.

So i set mouse wheel scrolling speed to a higher value: 7 lines per mouse-wheel tick.

It had some effects:
- in kate the scrolling speed went up -> good
- with vivaldi scrolling speed stayed the same -> bad
- firefox scrolling speed was manually adjusted as mentioned earlier in this thread

Why is this such a pain to have a convenient scrolling behaviour?
