You'll need to set the "libinput Accel Speed" property to a value between [-1, 1], where anything > 0 is faster than the default [1] <a href="https://wiki.archlinux.org/index.php/Mouse_acceleration">https://wiki.archlinux.org/index.php/Mouse_acceleration</a> I looked at your recording, and my calculations say you've moved your scroll motion by 4.5mm. That's not a lot, but libinput-debug-event says libinput is sending about ca 30 small scroll events, with a value of 1.48 pixels each (except two are 3px and one is 0.37px). Can you run libinput-debug-event and match the output with the visual output? maybe the events are lost in the xorg driver or the server? the finger movement before the scroll recording too shows a movement of less than 1mm. that's a pretty tiny movement, and half of that would be swallowed by the hysteresis of 0.5mm. Having said that, this is extremely fine-grained movement, is this really how you interact with the touchpad?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
