I can't start the virtual camera in OBS - ubuntu (framework 13)

I moved to apt because that is what the OBS recommends for ubuntu here.

Not suggesting you go to Flatpak just saying mine works out of the box installing just those two things.

So I finally figured it out. The necessary kernel module was not loaded. I just had to load it manually:

$ sudo modprobe v4l2loopback

And that’s it. Start obs and the virtual camera and you will have a new video device that you can use in your applications.

So much troubleshoot for such an easy fix.
