# Webcam is not working

## post by wolima78 on Feb 14, 2024

I realized that webcam is not working anymore. I can’t find any device at /dev/video*.

```lua

v4l2-ctl --list-devices
Cannot open device /dev/video0, exiting.
```

What system is this for?

Is this a USB camera or is this on a notebook and which notebook?

Commonly it is either:

- unplug/replug-in a USB Camera (so it reloads)
- Or confirm the driver is loaded

Check for drivers:

```bash
$ lsmod | grep video
```

Reload the driver would depending on camera/connection.

Also you can check:

```bash
$ sudo dmesg | egrep -i “video|camera”
```
