When I start cheese (with the webcam enabled with the Fn-F6 hardware key), I used to get the video from the webcam automatically after few seconds. Now the part of the cheese screen that should contain the video remains black. Also the small led next to the netbook webcam remains off (it used to light up showing the webcam was recording video). Cheese's screen remains blank but still cheese thinks there is a webcam available (while if I start cheese with the webcam disabled with the Fn-F6 hardware key, then cheese reports no webcam available, correctly). When the webcam is switched on with the hardware key Fn-F6, cheese preferences dialog shows a webcanm device "USB2.0 Camera (/dev/video0)". These are the attributes of the device: # ls -l /dev/video0 crw-rw----+ 1 root video 81, 0 Apr 24 13:52 /dev/video0 The user trying cheese is part of the video group. > What does "no video is received" mean exactly ?
