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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1587913 Title: Ubuntu 16.04 Two finger scrolling/multitouch not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1587913/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
