            Bug ID: 103201
           Summary: Wrong sensitivity for Elantech touchpad
           Product: Wayland
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: carlos.otgz at gmail.com

The sensitivity for my touchpad on the current version of libinput under
Archlinux is a bit incorrect. Specifically, tapping with one finger requires
too much pressure.

I have updated the pressure sensitivity by myself and now it feels as before:

$ cat /etc/udev/hwdb.d/99-touchpad-pressure.hwdb 
libinput:name:*ETPS/2 Elantech
Touchpad:dmi:*bvnAmericanMegatrendsInc.:*pnUX305LA*
 LIBINPUT_ATTR_PRESSURE_RANGE=10:8

Below is some information that might be useful in the correction of this bug:
