[Launchpad Bug Tracker <1219753@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

First I installed stock Ubuntu 13.04 Raring Ringtail with kernel 3.8.
Trackpad was functioning correctly (e.g. two-finger scrolling worked)
and was recognized as Synaptics device in /proc/bus/input/devices.

Due to very new Intel wireless 7260 hardware that did not work in kernel
3.8, I dist-upgraded to 13.10 Saucy Salamander with kernel 3.11. With
this kernel my Synaptics trackpad is no longer recognized as Synaptics
and works as default evdev pointer (mouse) device, without all the
trackpad features.

This bug report was done with kernel 3.11rc7, but applies also to kernel
3.10 and the latest saucy kernel 3.11 to which I'm upgraded by software
updater.

Instead of Synaptics, devices lists it as below:
