If you have an option in your BIOS to set the Touchpad to "Basic" mode (Acer devices have this option, for example), try that. If not, add i8042.nopnp to the vmlinuz line in grub.cfg and it should work fine.

Status in linux package in Ubuntu: Triaged Bug description: ASUS UX305-CA laptop with a clean install of Ubuntu 15.10 and touchpad will not work at all. It acts like it isn't even there. This is a dual-boot and touchpad works fine on Windows 10. Appears to be an Elantech touchpad according to driver details in windows but nothing in Ubuntu lists the touchpad. xinput -list shows no touchpad at all, just a virtual core XTEST pointer and my wireless mouse.
