Puntero no se mueve.

vi un caso igual al mio en este hilo: http://blogdrake.net/node/18618
en mi caso esto pasa cuando se pone la pantalla en negro despues de que se pone el protector de pantalla y no toco la maquina.
al mover el raton me muestra el escritorio (todo lo demas anda bien menos el puntero) en esa consulta piden el resultado de la ejecucion de este comando: cat /etc/X11/xorg.conf y este es el resultado:

mi raton es optico usb marca acer
mi pregunta es: existira alguna orden para decirle al ordenador que reinicie la funcion del raton? otra cosa: cuando el puntero se congela, el raton sigue emitiendo la luz.
