I'm using a laptop running Ubuntu 18.04 with one built-in webcam (integral to the monitor), and I'm attaching multiple other webcams.
I'd like to disable the built-in webcam only, and continue to allow for as many other cameras as I choose to connect. Is there an elegant way to do this in Ubuntu 18.04?
All the current info I can find on this topic suggests
sudo modprobe -r uvcvideo and
sudo modprobe uvcvideo to disable and enable webcams temporarily and editing
/etc/modprobe.d/blacklist.conf to disable webcams persistently after a reboot, but both of these methods seem to turn on or off all webcams, not only the built-in webcam or a certain specified webcam.
