[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".

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

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
