I have Ubuntu 21 04 installed on a Lenovo ThinkPad T14 Gen 2i and my integrated camera stopped working. It is detected but just showing black.

My kernel version is:

5.11.0-40-generic

My integrated camera is displayed in the output of lshw:

              *-usb:2       
                   description: Video
                   product: Integrated Camera
                   vendor: Azurewave
                   physical id: 4
                   bus info: usb@3:4
                   version: 60.04
                   serial: 0000
                   capabilities: usb-2.01
                   configuration: driver=uvcvideo maxpower=500mA speed=480Mbit/s

The output of lsusb shows on it:

Bus 003 Device 005: ID 13d3:5406 IMC Networks Integrated Camera

Output of v4l2-ctl --list-devices:

    /dev/video0
    /dev/video1
    /dev/video2
    /dev/video3
    /dev/media0
    /dev/media1

And the permissions of these files are:

crw-rw----+ 1 root video 81, 0 Nov 23 15:43 /dev/video0
crw-rw----+ 1 root video 81, 1 Nov 23 15:43 /dev/video1
crw-rw----+ 1 root video 81, 2 Nov 23 15:43 /dev/video2
crw-rw----+ 1 root video 81, 3 Nov 23 15:43 /dev/video3

I have tried changing the permissions of /dev/video*.

An external camera works.

Also in Software & Updates > Additional Drivers there are No additional drivers.

Any ideas? Thanks in advance!

This laptop has a Webcam privacy shutter Since the screen is black It sounds to me like that is the issue. Did you verify that it's open?

Yes, it was the privacy shutter! I did not know about this setting. Thank you very much!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
