Comment 34 for bug 1587913

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.
