Hey all!
So, after upgrading to Fedora Workstation 41 today I noticed that my built-in camera on my laptop is no longer recognised. Anyone else experiencing this? How do I solve it?
I ran a lsusb:

$ sudo v4l2-ctl --list-devices
Cannot open device /dev/video0, exiting.
Following Ben’s link, i tried a few things :
sudo lsmod | grep uvcvideo returned nothing.
Installing gucview worked, but launching it says no video device (/dev/video0) found
I’m at a loss about what is happening. What should i try to diagnose it ?
Thanks in advance, and cheers !

You first have to install v4l-utils (
sudo dnf update
sudo dnf install v4l-utils)
Having installed v4l-utils, I started jitsimeet in Firefox. And in the following system->video I could choose a usbdevice. This was followed by a dialog in which I could give permission.
That seems to be exclusively for USB connected cameras, not for internal laptop cameras. The article is also over 8 years old and the commands are no longer working, it seems.
