On my Gigabyte P57W laptop (and possibly others, see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1526393 ) my ETPS/2 Elantech touchpad is inconsistently detected at boot. Sometimes it's there, sometimes it's not, and I'm not sure of the circumstances which cause it to be detected or not. I'm on a 4.4 kernel, but trying a mainline 4.6 kernel did not help.
Luckily, after trawling the internet ( http://askubuntu.com/questions/636350/elantech-touchpad-not-detected-anymore-on-ubuntu-15 ) I found that adding `i8042.kbdreset=1` to `GRUB_CMDLINE_LINUX_DEFAULT` in /etc/default/grub resolves the problem.
The device is id=17 on xinput below. I *would* be running `lspci`, but my hardware is new enough that causes my machine to hang sometimes, but that's another bug...
