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.

It might just be glitched. Have you tried restarting?– wjandreaMar 25, 2017 at 13:52

@NeoTheThird shameless plug, but this most probably readily available and thus cheaper: askubuntu.com/a/779909/75166– MadMikeMar 27, 2017 at 13:15

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.

5Just run
lsof /dev/video0. That's often much faster than running lsof on all files– smac89Jun 2, 2020 at 4:58
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.

sudo rmmod -f uvcvideo(to kill laptop camera)sudo modprobe -r uvcvideo(to restart the video module)sudo modprobe uvcvideo(to restart the laptop camera)sudo modprobe -a uvcvideo(can be used while skipping steps 2&3 to restart the camera directly)
If you know the application name, you can use the following to get the process ID:
ps -fA | grep application_name
Output: process_name PID PPID .....
Then you can kill the process using:
kill -9 PID
