$<br><br><br></div>The setting "Horizontal Scroll Enabled" does enable/disable the thumbwheel.<br>I could also see that the thumbwheel uses button events (buttons 6 and 7, for each scroll direction)<br><br>Question is: is there a way to lower the "sensitivity" of the horizontal scrolling wheel with libinput? something equivalent to "scrolling distance" in evdev?<br><br><br></div>
