Public bug reported:
The output from touchpad-edge-detector
Touchpad AlpsPS/2 ALPS DualPoint TouchPad on /dev/input/event7
Move one finger around the touchpad to detect the actual edges
Kernel says: x [0..2000], y [0..1400]
Touchpad sends: x [92..1837], y [113..1308] \^C
Touchpad has no resolution, size unknown
Calculate resolution as:
x axis: 2000/<width in mm>
y axis: 1400/<height in mm>
