Agree 100%. On a slightly related note, the touchpad identifies itself as "SynPS/2 Synaptics Touchpad," though I'm not 100% sure it's a synaptics device.

It depends which Chromebook you are using, as there are a variety of touchpads used from Synaptics, Cypress, Atmel, etc. Also, make sure the chromeos_laptop kernel module is loaded.

As Ron pointed out, this is really not an appropriate forum to get help on touchpad issues. I suggest chromium-os-discuss mailing list for that: https://groups.google.com/a/chromium.org/forum/#!forum/chromium-os-discuss

I foundnd the mouse moved ever so slightly when I touched or released the pad -- so I changed the expected finger size:

xinput | grep 'SynPS/2' # to get the device id, should be 11

xinput list-props 11

# change "Synaptics Finger (271)"
xinput --set-prop 11 37 42 0 # 37=min size of a finger, 42=max size of a finger

# the previous value was: xinput --set-prop 11 25 30 0
