How to test Webcam on Manjaro Linux

Webcam setup on Manjaro Linux and other user-friendly Linux distributions should be automatic. You can usually plug in your webcam and have instant access to it. If you have a built-in camera, that should also work without any extra configuration.

In this guide, we’ll go over testing a webcam on Manjaro and give some troubleshooting pointers in case yours isn’t being detected automatically.

Testing a Webcam on Manjaro

Plug in your camera (if it’s not built-in) and use the following steps to see some clues about how Manjaro is detecting your webcam.

  1. Open a terminal and type the following command:
    $ sudo dmesg | grep -i camera
    [    6.656705] uvcvideo 1-1:1.0: Entity type for entity Camera 1 was not initialized!
    [    6.656744] input: UVC Camera (046d:0990) as /devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.0/input/input13

  2. You can also use the following two commands to list webcam devices available on your system:
    $ ls -ltrh /dev/video*
    crw-rw----+ 1 root video 81, 1 Jan 16 09:27 /dev/video1
    crw-rw----+ 1 root video 81, 0 Jan 16 09:27 /dev/video0


    $ v4l2-ctl --list-devices
    UVC Camera (046d:0990) (usb-0000:00:14.0-1):
  3. Configurable options such as brightness, zoom, etc. are viewable with this command (you may need to substitute video0 with a different device name):
    $ v4l2-ctl -d /dev/video0 --list-ctrls
  4. You can use the cheese application to utilize your webcam and record videos or take pictures with it. Install it by executing this command in terminal:
    $ sudo pacman -S cheese
  5. To open it, search for it in your application launcher:
    Open Cheese (or any applicable program) to use your webcam

    Open Cheese (or any applicable program) to use your webcam

    Or just use the following command in terminal:

    $ cheese


That’s all there is to it. Cheese is just one of many video capture programs available for Manjaro; feel free to install one or more of your favorites. As long as the above commands are indicating that your webcam is discoverable, then any video capture program should be able to utilize your webcam.
