[Bug 1265885] Re: regression: SynPS/2 touchpad detected as DLL060A:00 pointer

 

So I loaded the module, there are no messages generated in dmesg as a
result.

Also, I ran this in another window while loading the module just to make sure:
# udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[1230.288508] add      /module/hid_multitouch (module)
KERNEL[1230.288646] add      /bus/hid/drivers/hid-multitouch (drivers)
UDEV  [1230.289076] add      /module/hid_multitouch (module)
UDEV  [1230.289442] add      /bus/hid/drivers/hid-multitouch (drivers)

Looks like the only udev events are related to the module and driver
load. There's nothing about the input device itself.

Also, no new devices show in "xinput list".

Title:
  regression: SynPS/2 touchpad detected as DLL060A:00 pointer

Status in Release Notes for Ubuntu:
  Fix Released
Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Committed

Bug description:
  This regression occurs somewhere between 3.11.0-14-generic (latest on
  saucy) and 3.13.0-031300rc6-generic (a test kernel). On the earlier
  kernel, I actually  get settings for setting up my touchpad in the
  unity interface. With the updated kernel, those options disappear. I
  only get one set of options both my mouse and my touchpad instead of
  each one independently. It means that I can't set the pointer speed
  differently or turn on natural scrolling for my touchpad.

  WORKAROUND: Execute at a terminal and then reboot your system:
  echo "blacklist i2c_hid" | sudo tee -a /etc/modprobe.d/blacklist.conf

  Release Notes Text
  Bug:1265885 On some Dell XPS13 systems the Synaptics touchpad is incorrectly recognised as a mouse.  See the bug for possible workarounds.
