I was using facebook messenger, and When I finished my call, the web cam stilled working.I have an integrated camera in my laptop HP 630. Is there a way to turn it off ? Thanks.


If the webcam behaves weirdly, not automatically turning off for example, you can:

To disable the webcam run:

sudo modprobe -r uvcvideo

It removes the module from the Linux Kernel.

To re-enable the webcam you can either restart or run:

sudo modprobe -a uvcvideo

Reinserts the module.


Thank you guys, the problem is gone.

- I used the command : lsof | grep video0 to find the software using my webcam. It was FireFox.

- I just restarted FireFox, and then the webcam turned off.
