--- Comment #4 from Jens Westemeier <jens_westeme...@web.de> --- 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 😄 -- You are receiving this mail because: You are watching all bug changes.
