Touchpad pressure settings for Latitude E5410
Summary
The existing pressure values (down:up) are very wrong for this ALPS touchpad. The correct pressure range is approximately 105:100. With this setting in /etc/libinput/local-overrides.quirks the touchpad is much more usable.
Steps to reproduce
Start moving a finger across the touchpad and slowly lift it. Observe that the pointer continues to follow the finger after the finger leaves the touchpad surface. Notice how hard it is to position the pointer accurately because the pointer moves as the finger is lifted.
