Web cam not working on ThinkPad P14s AMD Ubuntu 20.04

Question

The integrated web cam on the ThinkPad P14S AMD is not working while running on Ubuntu 20.04

I run lsusb and I get the following

I run uname -r

5.11.0-27-generic

I run but nothing happens

sudo modprobe -r uvcvideo && sudo modprobe uvcvideo

When I attempt to run cheese - this is what I see black screen

I did find this https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1881757 but not much of an update February

Any tips?

Thanks!

Try to install v4l-utils with

$ sudo apt install v4l-utils

After that try:

v4l2-ctl --list-devices

You should see the list of all video device, and should be something like

/dev/video0
/dev/video1

Then try cheese with some of the video device you've got. For example cheese -d /dev/video0 and cheese -d /dev/video1 and so on.
