Logitech Marble Mouse

[Beerislife]

I usually follow the instructions here to get the mouse ball to function as a wheel but I can't get it to work in Kubuntu 17.10

Any idea what's changed?

Cheers.

If anyone else needs this, I believe it needed these changes:

sudo nano /usr/share/X11/xorg.conf.d/10-libinput.conf

and add:

Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Driver "libinput"
Option "ScrollMethod" "button"
Option "ScrollButton" "8"
Option "MiddleEmulation" "on"
EndSection

If that doesn't work, then try this:

sudo nano /usr/share/X11/xorg.conf.d/10-evdev.conf

Add:

Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "8"
Option "XAxisMapping" "6 7"
Option "Emulate3Buttons" "true"
EndSection

In either case, change 8 to 9 if you want to use the right button to activate scroll on this line: Option "EmulateWheelButton" "8"
