Bug#237371: tap-to-click

[Ari Pollak <ari@debian.org>]

I don't know if this is really an answer or not, but to get tap-to-click 
functionality for a Synaptics touchpad in X, one would have to install 
the xfree86-driver-synaptics package or tpconfig. I don't know if this 
behavior used to be in XFree86 prior to 4.3.0.
