How do I enable Extra Visual Effects using an Intel graphics controller?

Question

I'm using an office desktop computer with Ubuntu 10.04 installed. I know the Intel graphics controller should be able to pull off the simple desktop effects made available by Compiz, but I can't convince Ubuntu to try. When I try to enable Extra Effects it pops up the "Hardware Drivers" dialog and concludes after a while "No proprietary drivers are in use on this system", with the list below empty.

Note, I used to have nVidia drivers installed. I moved the SSD from my old computer to this new one.

I would like to know what I must learn in order to enable Extra Effects on Ubuntu using Intel graphics controller
