[Bug 1258837] Re: [Dell Latitude E7440] ALPS touchpad keeps having state reset
I just wanted to let everyone know that Pali's fixes made it upstream
and were CC'ed @stable and have landed across Ubuntu already. Anyone
that has been affected should be able to update their kernels to get the
patches.

Bug description:
The mouse cursor keeps on jumping around, and these messages appear in the log when it happens:

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.
