<pre>The update from libinput 1.7.1 to 1.7.2 causes the touchpad on Acer C720 to
need more pressure than before. I followed this page to adjust the settings and
am filing this bug to get the pressure changes in the repository
<a href="https://wayland.freedesktop.org/libinput/doc/latest/touchpad_pressure.html">https://wayland.freedesktop.org/libinput/doc/latest/touchpad_pressure.html</a>.
Here are the settings that seem comfortable to me:
$ cat /etc/udev/hwdb.d/99-touchpad-pressure.hwdb
