I have a Lenovo T410 with an inbuilt webcam and I haven't been able to get the webcam working. I tried skype, cheese, both just give me a black window. The microphone works fine with skype, by the way. Can anyone provide any clues please? The webcam is enabled in the bios, but there is no light indicating the webcam is on (not sure if there should be, though). I tried this on Kubuntu 11.10 and have upgraded to 12.04 with the same results. The Fn-F6 keyboard combination doens't seem to do anything either.

EDIT: I got the webcam replaced, it looks like it was a hardware problem, because it works fine now. Thanks guys.

Here is the output from guvcview, minus lots of lines describing the available capture formats. It says "unable to start with minimum setup. Please reconnect your camera.".

Hmm, it doesn't work in windows either. I'm thinking hardware issue. –  kristianp May 13 '12 at 5:20

If you are 100 % positive it's enabled in the BIOS (F1 → Security → I/O Port Access → Integrated Camera), and it's also not working in Windows, then maybe the camera is broken? I'm not sure about the differences between the camera hardware, but the one in my T510 works fine out of the box. –  htorque May 17 '12 at 7:29
    
@htorque yeah, I'm going to get it warranty-serviced. I checked the bios settings. –  kristianp May 17 '12 at 9:36
    
Not a real solution, but try this. Exit all browsers and try to use the webcam. –  Flo Jun 19 '12 at 19:35
    
Thanks for the feedback. I got the webcam replaced under warranty and it works fine now. –  kristianp Jun 20 '12 at 2:33

The output from guvcview is in my post. i.e. it's already installed. –  kristianp May 23 '12 at 12:05
