Not sure if this helps, but i've been struggling with these issues since 12.04 (see bugs #1166442 and #1272777). There have fixes in 3.15.05 and later ones, but this issue occured again with kernels 4 and ongoing. Other than using these kernels, I have not found an approriate solution.
May this can help fix this. I'm using a Gigabyte U2442n laptop with an older Elantech touchpad. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1587913 Title: Ubuntu 16.04 Two finger scrolling/multitouch not working Status in xserver-xorg-input-synaptics package in Ubuntu: Confirmed Bug description: I've done a fresh install of Ubuntu 16.04 on my Asus G501 but the two finger scrolling isn't working. The touchpad works but sometimes after restarting it doesn't get detected and so I have to shutdown in order to get it working again.
