I have just installed Fedora v10 on a venerable T21 laptop, using the Live CD. I intend now to do a real installation. But I find that the installed mouse (a USB Logitec trackball known to be in good condition) doesn't produce any motion or action. The little navigation joystick and its button do work, but that's clumsy and I don't like it.

There must(?) be a way to switch the mouse function to the mouse. Can someone tell me what it is>
