i won't bag on you for not searching first, as you obviously did so. search refinement though, is a very good subject to always be improving upon, for any of us. it's a key fundamental for anyone in *any* IT position.
"Edit the /usr/lib/X11/xorg.conf.d/10-synaptics.conf using nano or kate and add the line: Option "MaxTapTime" "0" to first the first section"
is what you would have found using a more specific search string. you should not be spending hours at a time over something so apparently simple. ever. we are not making heart valves, nor are we reinventing the wheel. if you run into a problem, chances are 99% someone has already encountered it and a fix/workaround has been published.
being your first post here, welcome to the grinder you're going to love it.
