@Kyle Fazzari - it turns out that my laptop has an Alps touchpad rather
than a Cypress one, so the fix would have no effect for me anyway..
Searching for the error message had brought me here, so I presumed it
was the same issue. I've opened up a separate bug for the Alps touchpad
(see #1258837).

Status in “linux” package in Ubuntu:

Status in “linux” source package in Precise:

Status in “linux” source package in Quantal:

Bug description:
  I installed Kubuntu 12.04 with ppa suggested on this forum but I still
  have intermittent problem with touchpad.I also install kde-config-
  touchpad and have full control on touchpad(ex.: disable when mouse
  plugged).

  It work like I want but after come back from sleep mode, I got error message about synaptics and the syslog look like this:
  Sep  9 10:28:34 XPS-L321X kernel: [ 6839.441575] psmouse serio1: Trackpad at isa0060/serio1/input0 lost sync at byte 1
  Sep  9 10:28:34 XPS-L321X kernel: [ 6839.442852] psmouse serio1: Trackpad at isa0060/serio1/input0 - driver resynced.

  These lines are repeated in infinite loop.

  I tried these command:
  sudo modprobe -r psmouse
  sudo modprobe psmouse

  It reassign input:
  input: CyPS/2 Cypress as /devices/platform/i8042/serio1/input/input17
  It stop the loop for 2 minutes and start again

  Only way to fix is restart x session
