evemu log with some movement and tapping

Thanks for your answer! Sorry, I didn't find the page you linked before. Some
more info:

Lenovo Thinkpad W530
(dmi:bvnLENOVO:bvrG5ETA5WW(2.65):bd03/04/2016:svnLENOVO:pn2447GZ2:pvrThinkPadW530:rvnLENOVO:rn2447GZ2:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable:)

Touchpad physical dimensions are roughly 75x45mm. It's a normal non-clickpad
with two physical buttons.

And finally, touchpad-edge-detector:
Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event14
Move one finger around the touchpad to detect the actual edges
Kernel says:    x [1472..5470], y [1408..4498]
Touchpad sends: x [1250..5631], y [1197..4834] \^C

Touchpad size as listed by the kernel: 66x36mm
Calculate resolution as:
        x axis: 3998/<width in mm>
        y axis: 3090/<height in mm>
