I recently purchased an Acer C720P and installed Ubuntu 16.04 64bit (using Unity) on it. I did a full installation (not using Crouton). Everything works perfectly - except for the touchpad. The touchscreen works fine.
I've tried various fixes that I've found from Googling but nothing seems to make any difference, ex:
I've read things that say synaptics won't work, use libinput, and I've read things saying libinput won't work, use synaptics drivers. I've tried uninstalling all packages for one and installing the other. Same results after reboot. The touchscreen always works fine, and the touchpad has no response at all.
synclient gives the output
Couldn't find synaptics properties. No synaptics driver loaded, and I do not see a touchpad tab under System Settings > Mouse & Touchpad.

Is there anyone who has gotten this working, or can point me in the correct direction?
