** Description changed:

  My webcam used to work. It doesn't work anymore. I've tried cheese and
  gstreamer-properties. The LED indicator does turn on but then nothing
  happens. It just hangs.  I am not sure how to check what kind of webcam
  hardware I have. I have a thinkpad x300 with a builtin webcam. The green
  LED  of the webcam turns on when trying to use it from cheese or
  gstreamer-properties but I am not getting any video. Gstreamer-
  properties just keeps showing "Testing..." and nothing else happens.
