@Brian,
You could install 3.16 kernel with "sudo apt-get install linux-generic-lts-utopic" command, but I think it's fixed in 3.13 kernel.

After re-tested with newer kernels, I noticed that with the 14.04 stock kernel (3.13.0-24), there is no "Synaptics Touchpad" in xinput output:
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ DLL063E:00 06CB:2934                    	id=11	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]

    ↳ Power Button                            	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]

    ↳ AT Translated Set 2 keyboard            	id=12	[slave  keyboard (3)]
    ↳ Dell WMI hotkeys                        	id=13	[slave  keyboard (3)]

"Synaptics Touchpad" will appear with 3.13.0-29, scrolling does not work
too.

However, after upgrade to 3.13.0-32 (or use 14.04.1 stock image), scrolling works as expected.
This also applies to the latest update (3.13.0-46 kernel).

Therefore I will close this bug with fix-released.
For those who still affected, please try to run "sudo apt-get dist-upgrade" to upgrade your kernel. Or give 14.04.1 / 14.04.2 a try.
If it's still not working, please feel free to open a new bug with "ubuntu-bug linux" for it.
Thanks!

Title:
  [Dell Inspiron 5547/5447] Unable to scroll with the clickpad

Status in HWE Next Project:

Bug description:
  CID: 201401-14530 Dell Inspiron 5547

  The Clickpad on this system was detected as a SynPS/2 Synaptics TouchPad, I'm not sure if this is expected, but the scrolling feature is not working on 14.04 + update(both two fingers scrolling and one finger edge scrolling).
  Also, the "disable while typing", three and four fingers tapping are not working as well.

  Steps:
  1. Install 14.04 + update (3.13.0-29), boot to desktop
  2. Test the touchpad

  Expected result:
  * At least edge scrolling should work

  Actual result:
  * Only left / right click, one-finger single / double tapping works.
