yeah, the synaptics driver doesn't really handle multitouch correctly. half of
that is legacy code, the other half the nightmare of rewriting much of the
driver without breaking all options that synaptics provides. so when we added
software buttons, we added the ability for the middle button.
amongst other things, such historical accidents are what we're trying to get
rid of in libinput.

yeah, three finger tap and click with three fingers down will both trigger the
middle click. the latter doesn't work with libinput yet (<a class="bz_bug_link

right. what I'd like to focus on is making the left+right middle click less
fiddly so it is a reliable way of triggering middle clicks. If you could help
us out with that, that'd be appreciated. Meanwhile, I think I'm going to stand
by my "no middle software button" stance.</pre>
