How do I adjust the pointer speed and scrolling speed of a trackpad?

This is the only way I can think of that might change pointer speed beyond the default allotment. It might not work.

Install dconf editor:

sudo apt-get install dconf-tools 

Run dconf-editor and navigate to:

org -> gnome -> settings-daemon -> peripherals -> touchpad  

There you can play around with the value of motion-acceleration. The max value that System Settings gives is 10, so maybe setting it to 20 would work.
