Веб-камера на XPS M1530 не работает с 12.04 [закрыто]

У меня Dell XPS M1530, который изначально поставлялся с Ubuntu (примерно в 2006 году). Веб-камера всегда работала из коробки в Cheese, Skype и т. Д. Я не пользуюсь ею регулярно, но я проверял это раньше. Я недавно попробовал его после обновления до Ubuntu 12.04, и я получаю черный экран в каждом приложении, которое я пробую. (Синяя подсветка веб-камеры горит, я просто не получаю видео.)

Вот что я понял:

• Это моя веб-камера, как сообщает [ 113]: Bus 003 Device 003: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam
• Должны поддерживаться драйверами UVC: http://www.ideasonboard.org/uvc/#devices
• Во всех приложениях протестировано, синий свет включается, но видео черное.
• Вывод сыра:

• Вывод Skype (одна ошибка появлялась каждый раз, когда я отключал видео. Нет ошибки при включении видео, но, конечно, только черный экран и синий свет.
