    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?
