I can only find scroll methods support in libinput.

https://www.mankier.com/4/libinput http://wayland.freedesktop.org/libinput/doc/latest/group__config.html

How can I change the scroll speed of my bluetooth mouse? No relevant prop in my xinput list-props.

libinput Accel Speed (276):     0.000000
    libinput Accel Speed Default (277):     0.000000
    libinput Natural Scrolling Enabled (278):       0
    libinput Natural Scrolling Enabled Default (279):       0
    libinput Send Events Modes Available (257):     1, 0
    libinput Send Events Mode Enabled (258):        0, 0
    libinput Send Events Mode Enabled Default (259):        0, 0
    libinput Left Handed Enabled (280):     0
    libinput Left Handed Enabled Default (281):     0
    libinput Scroll Methods Available (282):        0, 0, 1
    libinput Scroll Method Enabled (283):   0, 0, 0
    libinput Scroll Method Enabled Default (284):   0, 0, 0
    libinput Button Scrolling Button (662): 2

  • I am not sure if that's what you want, but systemsettings5 of KDE does have Mouse wheel scrolls by textbox measured in lines. I bet other DEs have a similar option.

This has been answered on Unix & Linux by meuh

In short,

there is no current api for changing the scroll speed for libinput devices

so other methods must be used to solve this issue.

Implementation of this feature has been delegated to toolkits.

Here is a GNOME issue and two KDE issues tracking it:
