That's fine. Two-fingered scrolling is all I really care about.

Yes, that test indicates that the driver is working.

Ok. When I do that, I see:
dcramer@anatine ~
$ xinput --list-props 13
Device 'AlpsPS/2 ALPS DualPoint TouchPad':
Device Enabled (121): 0
...
When I run:
dcramer@anatine ~
$ xinput --set-prop 13 "Device Enabled" 1
The command completes without any error or output, but the touchpad
doesn't start working and when I run --list-props again, "Device Enable"
is still set to 0. If I do --set-prop while tailing /var/log/Xorg.0.log,
I see:
[ 9830.351] (--) AlpsPS/2 ALPS DualPoint TouchPad: touchpad found
Let me know if there are any other things I can try or if there's any
other information I can provide.
Thanks,
David
