comment #76 by FZ (sirfz):

I installed Ubuntu 17.04 on mu new G752VS yesterday and the ELAN 
Touchpad was completely non-functional. Today, out of no where and 
without any reasonable explanation, it started working after a resume 
from sleep (opened lid). Right now it's fully functional, both buttons 
are working as well as tracking and multi-touch gestures (e.g. 
double-finger scrolling). All I did was install a few updates using the 
Software Updater today.
