            Bug ID: 102206
           Summary: Swipe and pinch gestures non-functional on Lenovo P51
                    and P71
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: benjamin at sipsolutions.net

I noticed that while most operations work just fine on the P72/P51 the swipe
and pinch gestures seem to be really hard to trigger.

The reported size and input range of touchpad in question seems to be
reasonable:

15:47:32 INFO | Reported X range for Touchpad from 1266 to 5676 (resolution 45,
size 98.0000mm).
15:47:32 INFO | User X range for Touchpad from 1265 to 5677 (resolution 43,
size 101.0000mm).
15:47:32 INFO | Reported Y range for Touchpad from 1094 to 4762 (resolution 69,
size 53.1594mm).
15:47:32 INFO | User Y range for Touchpad from 1093 to 4832 (resolution 67,
size 55.0000mm).

I'll attach an evemu dump in a bit.
