Comment 10 for bug 1773597

This problem may be associated with the USB software. I shut down the machine and pulled the battery and the Logitech mouse USB receiver. Booted the machine. With just the sign-in box on the screen, both the mouse and the trackpad worked. Immediately after sign-in the mouse could not be controlled by the trackpad. The keyboard continued to work. I rebooted the machine after removing the Logitech USB receiver. The trackpad would not work. I inserted the Logitech USB receiver, but it did not allow the mouse to work. Rebooting reactivated the Logitech mouse.
