Raramente uso cd's en mi computadora portátil, pero recuerdo haber tenido el mismo problema hace unos meses. Cuando pongo un CD en mi unidad de DVD no pasa nada. Se activó la última vez sin que yo hiciera nada, pero no sé qué pasa. Necesito grabar un cd con k3b pero me da el error "no se encontró ningún dispositivo óptico".
Mi sistema es Fedora 20 x86_64. Problema: los CD no se montan, cuando se inserta en la unidad no pasa nada.
¿Qué puedo hacer para resolver este problema?
ACTUALIZACIÓN ACTUAL: Problema: los cd y dvd no funcionan correctamente, ya que han sido inestables como en "no montar cuando se inserta", "montar cuando se inserta pero desconectar al azar" / "desmontar al azar", cuando se desconecta el disco es invisible al sistema y no puedo expulsar el disco.
Puse una película de DVD en la unidad ayer, se montó en / run / media / username / MOUNTPOINT y todo funcionó, luego, después de un tiempo, desapareció, ya no estaba montada y no puedo expulsar el DVD de la unidad. Así es como está ahora, todavía está en la unidad, aquí hay algunos comandos que funcionan en la unidad como está ahora:

El comportamiento de la unidad de DVD, los discos y los DVD están montados /run/media/username/MOUNTPOINT
y funcionan, pero luego pueden desconectarse en cualquier momento, y cuando se desconectan, no aparecen en ninguna parte del sistema, y no puedo expulsar el disco.
Cuando cierro la tapa, la computadora portátil está configurada para "dormir", lo hice hace 4 horas, y cuando la revoqué hace una hora, se instaló el DVD en la unidad /run/media/username/MOUNTPOINT
. Así es como es ahora:
