        <pre>It gives me this:

Touchpad AlpsPS/2 ALPS DualPoint TouchPad on /dev/input/event6
Move one finger around the touchpad to detect the actual edges
Kernel says:    x [0..2000], y [0..1400]
Touchpad sends: x [97..1823], y [177..1299] |
^C

Touchpad has no resolution, size unknown
User-specified touchpad size: 80x40mm
Calculated ranges: 1726/1122

Suggested udev rule:
# <Laptop model description goes here>
evdev:name:AlpsPS/2 ALPS DualPoint
TouchPad:dmi:bvnDellInc.:bvrA19:bd11/14/2013:svnDellInc.:pnLatitudeE6320:pvr01:rvnDellInc.:rn0GJF11:rvrA01:cvnDellInc.:ct9:cvr:*

 EVDEV_ABS_35=97:1823:22
 EVDEV_ABS_36=177:1299:28

Another time I got this:
Touchpad sends: x [73..1806], y [166..1307]</pre>
