I am coming from Ubuntu 18.10 where everything was working, the webcam does not seem to be detected in Juno. There is no on/off key for the webcam on the XPS as far as I know. The webcam is enabled in the BIOS and I always update to the latest versions from Dell.
Stock Camera app gives me a dark window while auto brightness in Settings, which I believe is governed by the webcam, does not seem to work.
sudo modprobe -a uvcvideo to no avail.
lsblk gave me uvcvideo 0, I think it means Juno is not starting the webcam.
Thank you, I am a Linux newbie, any help is very much appreciated.
Update: when opening the Camera app, there is now the following message, while before there was just a black window.
