Speed up your Synaptics touchpad in Ubuntu

The synaptics touchpad found in many Dell machines and others is extremely slow in the default Ubuntu installation. Manipulating the mouse settings in the preferences doesn’t help either, so what to do? Using it when this slow becomes really frustrating in the long run.

Luckily I came across a post by aboe on the Ubuntu forums, which suggested some additional options in the synaptics section of xorg.conf. After trying this out, the touchpad immediately felt snappier and is finally useful!

I have copied the configuration here for reference, if the original post ever disappears.
