    Updated: My Logitech C920 webcam shows 2 blue curved LEDs on each side when used by a program. Some only enable the LEDs when it is actually grabbing images/video (chromium is like this) and others show the LEDs all-the-time (guvcview), which I suppose means the program is grabbing video always.

    Is yours fancy, perhaps with autofocus or IR? It is from 2015-ish.
    I don't leave the webcam connected. It is only connected when joining a video call. Common sense security.

    v4l2-ctl -l will show the possible settings. I routinely set the zoom and brightness this way for consistency. I don't see any LED controls in the list of options. Example cmds:
    Code:
    v4l2-ctl -d /dev/video0 -c zoom_absolute=200
    v4l2-ctl -d /dev/video0 -c brightness=100

    Have you checked the manual of your camera? Ubuntu may not even be aware of the existence of that green led.

    Mine has a green light that is on whenever a program like Cheese or guvcview or OBS is using it. However, when the program is closed the light goes off.

    And mine, which is an old (12 yrs) Logitech of unknown model number, but without microphone, is just like Autodave's, showing a light only when actively working.
