Was trying to troubleshoot this after I got my 720 yesterday day and
this thread was a godsend, I downloaded the latest stable kernel,
applied the line patch and it worked perfectly. Thanks!! :D
But I think one issue that I am running into is what others mentioned
above, I have to power cycle/reboot one or more times to get the machine
to boot into Ubuntu, otherwise I just get a black screen and it hangs. I
think it was mentioned above that it was a problem with GRUB mostly, is
there an easy way to fix that ?

Bug description:
SRU Justification:
[Impact]
Touchpad on Lenovo X1 Yoga / Yoga 720-15IKB does not work.
[Test Case]
Touchpad doesn't work on the system.
With the patch, touchpad works.

Minimal. The it adds a device ID to intel-lpss-pci, so it's limited to
one device.

Touchpad is not automatically detected in 14.04, 16.04 or 17.04. I
tried in live mode and after full installation. I was able to connect
an external mouse and a bluetooth mouse and both worked. I checked my
xinput list and no sign:
