I have an old Dell XPS 15 laptop running Ubuntu 16.04.3. I've always been experiencing annoying touchpad gesture behavior, for example when I try to scroll (2 fingers) and I touch the bottom of the touchpad, my unity menu always opens and then it activates whatever icon is under the cursor.
I'd like to disable it but I have no idea how to. I've searched through some other people's questions but could not find an answer for it.
Here is my (default) synclient configuration:
$ synclient

Not sure if it matters, but I only have this issue when I scroll up and start my fingers at the bottom edge of the touchpad.
