| Subject: [PATCH] Disable smooth scrolling in xf86-input-evdev. |
| |
| This caused additional valuator-containing motion events to |
| be sent on behalf of the scrollwheel, which Chrome treated |
| identically to touchpad scroll events, resulting in the |
| scrollwheel being unusable. |
| |
| BUG=chromium:118608 |
| TEST=manual: we scroll 106 pixels for each scrollwheel click on stumpy |
