Public bug reported:

This is very similar to bug 1048258 - the mouse cursor keeps on jumping
around, and these messages appear in the log when it hapepns:

The touchpad is recognised as a "AlpsPS/2 ALPS DualPoint TouchPad". This
is occurring with Ubuntu 13.10, though I have also seen this behaviour
in the version of Linux Mint based on Ubuntu 13.04.
