            Bug ID: 95314
           Summary: libinput throws error on 3-finger swipes on Synaptics
                    touchpad

           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium

libinput-list-devices output

I have an ASUS P53E laptop with a Synaptics touchpad.

libinput-debug-events recognizes the 3-finger gestures, but prints an error on
each update:

libinput error: libinput bug: Event for missing capability CAP_GESTURE on
device "SynPS/2 Synaptics TouchPad"

Both Wayland and Xorg are equally affected.

I use Debian Sid with libinput 1.2.4. (1.2.4-1 package)

The gestures work fine if I workaround the capability check by making it always
return 1, so the hardware is indeed capable to do that.
