I've disabled suspend on the laptop and continued to use the laptop so
that even the screensaver doesn't kick in. I've also removed resetafter
kernel parameter.

I booted the laptop with both kernels, ran "tail -f /var/log/kern.log"
in a terminal and left it running until I saw error messages (and when I
did, I ran "uname -a" to ensure I was running with the right kernel):

Running with Saucy's kernel:

Title:
  [Dell Latitude E7440] ALPS touchpad keeps having state reset

Status in “linux” package in Ubuntu:
  Incomplete

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

  Dec  7 21:57:26 wyvern kernel: [  648.148833] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - driver resynced.

  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.
