Using the MX Master mouse that has two wheels: the standard scrolling wheel
('vertical scrolling') and a small "horizontal scrolling wheel" AKA
thumbwheel.In the past with evdev, it was possible to reduce the sensitivity of the thumbwheel (i.e. to have to rotate it more before it triggers an event) with: xinput set-prop 11 "Evdev Scrolling Distance" 1 2 1 With libinput, I couldn't find any equivalent property: xinput list-props 11 Device 'Logitech MX Master': Device Enabled (133): 1 Coordinate Transformation Matrix (135): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Accel Speed (269): -0.182511 libinput Accel Speed Default (270): 0.000000 libinput Accel Profiles Available (271): 1, 1 libinput Accel Profile Enabled (272): 1, 0 libinput Accel Profile Enabled Default (273): 1, 0 libinput Natural Scrolling Enabled (274): 0 libinput Natural Scrolling Enabled Default (275): 0 libinput Send Events Modes Available (253): 1, 0 libinput Send Events Mode Enabled (254): 0, 0 libinput Send Events Mode Enabled Default (255): 0, 0 libinput Left Handed Enabled (276): 0 libinput Left Handed Enabled Default (277): 0 libinput Scroll Methods Available (278): 0, 0, 1 libinput Scroll Method Enabled (279): 0, 0, 0 libinput Scroll Method Enabled Default (280): 0, 0, 0 libinput Button Scrolling Button (281): 2 libinput Button Scrolling Button Default (282): 274 libinput Middle Emulation Enabled (283): 0 libinput Middle Emulation Enabled Default (284): 0 Device Node (256): "/dev/input/event6" Device Product ID (257): 1133, 16449 libinput Drag Lock Buttons (285): libinput Horizonal Scroll Enabled (258): 1 $ The setting "Horizontal Scroll Enabled" does enable/disable the thumbwheel. I could also see that the thumbwheel uses button events (buttons 6 and 7, for each scroll direction) Question is: is there a way to lower the "sensitivity" of the horizontal scrolling wheel with libinput? something equivalent to "scrolling distance" in evdev?
