A full explanation of why and what is in the v1, v2 patch thread here: https://lkml.org/lkml/2018/11/22/625 v3 adds a better commit messages, m560 REL_HWHEEL_HI_RES support and a patch moved in the ordering. This is a full patch sequence because Benjamin's magic scripts struggle with singular updates ;) hid-tools patches to add the tests: https://gitlab.freedesktop.org/libevdev/hid-tools/merge_requests/12 libinput support (unmerged): https://gitlab.freedesktop.org/whot/libinput/tree/wip/hi-res-scrolling If you want to 'feel' how it works, run sudo ./builddir/libinput-debug-gui and watch the green/red scroll bars. On a device with hi-res scrolling the green bar (scroll fractions) will move smoother than the red bar (wheel clicks). Tested with: - Microsoft Comfort Optical Mouse 3000 - Microsoft Sculpt Ergonomic Mouse - Microsoft Wireless Mobile Mouse 4000 - Logitech MX Anywhere 2S And a few other mice that don't have that feature, so the testing was of limited excitement.
