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.
