Created attachment 178529 [details] udevadm_info Hello, I'm using a Logitech Marble FX Trackball Logitech. OS is Opensuse Tumbleweed. Libinput version is 1.27.1. This works fine under Plasma6 / X11 (/etc/X11/xorg.conf.d/99-Logitech-Marble.conf 99-Logitech-Marble.conf ). Under Plasma6 / Wayland the paste button is not working, MiddleMouseEmulation seems to be set, but can't be changed (only both big buttons simultaneously provide paste functionality). qdbus6 org.kde.KWin /org/kde/KWin/InputDevice/event4 gives qdbus6 Scrolling functionality could be set by: qdbus6 org.kde.KWin /org/kde/KWin/InputDevice/event4 org.kde.KWin.InputDevice.scrollOnButtonDown true libinput record (with one time paste button pressed) gives: libinput_record udevadm info gives: udevadm_info Thanks for your help, Jens

In the Mouse configuration I can assign any shortcuts. How can I assign the paste functionality?
Here a comment from libinput developer Peter Hutterer: Paste is usually in response to a middle button press but that button you're pressing? it produces BTN_SIDE. That one is sequentially button 4 which in X maps to button 8 (4,5,6,7 is reserved for scrolling). Which according to your xorg.conf you map into logical button 2 (together with button 9, which will be whatever produces BTN_EXTRA) - hence why it works for paste. In libinput/Wayland that button remains BTN_SIDE and that is passed up to the compositor and eventually to the Wayland client. What you need is a compositor functionality to remap that button into another button, equivalent to the ButtonMapping xorg.conf option. I don't know though if Plasma has that option but either way - that's where you need to ask 😄
Great info! You can re-map buttons on System Settings' Mouse page, which is I suspect where the trackball will appear. Can you try that?
My trackball appears in System Settings. Going to "Configure Extra Buttons -> Add Binding" I can press the small button, intended to perform the Paste operation. But how to assign the Paste operation in the second step? I pressed both left&right big buttons, which currently provide the Paste operation, but that does not work. It seems that at that stage only keyboard shortcuts are allowed.
