I've recently installed Ubuntu 18.04.01 on a Lenovo S540 laptop (full disk installation).
I have the kernel 4.15.0-43-generic and I had the same problem.
In my /etc/modprobe.d/blacklist.conf there was not module "i2c_i801" blacklisted, but still the touchpad would be inactive after a wake-up from suspension and it would come back after a restart.

Adding the parameter "psmouse.synaptics_intertouch=0" to grub solved the issue.
