XPS M1530 上的网络摄像头无法与 12.04 配合使用

我有一台戴尔 XPS M1530,最初是随 Ubuntu 一起提供的(大约在 2006 年)。网络摄像头在 Cheese、Skype 等应用中始终可以开箱即用。我并不经常使用它,但我之前曾测试过它。我最近在升级到 Ubuntu 12.04 后尝试了它,我尝试的每个应用程序都出现黑屏。(蓝色网络摄像头指示灯确实亮了,但我就是看不到任何视频。)

以下是我得出的结论:

  • 这是我的网络摄像头,据报道lsusbBus 003 Device 003: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam
  • 它应该得到 UVC 驱动程序的支持:http://www.ideasonboard.org/uvc/#devices
  • 在所有测试的应用程序中,蓝灯亮起,但视频是黑色的。
  • 奶酪产量:
