I boot the Knoppix CD with no parameters and it works awesome. Did an HDD install and the mouse won't work. What gives? The light is on and I can't find any errors, but the pointer just sits in the middle of the screen.

FYI, I had the same problem with Rehat and Mandrake. Why would the Knoppix CD work but the HDD not? Can I copy the config files from the CD setup to the HDD one? If so, which ones? The XF86Config-4 is exactly the same if I boot from CD or from the HDD... so the failure must be somewhere else.
