Disable the webcam kernel module:
modprobe -r uvcvideo
uvcvideo is the most common module name. If not found, check
lsmod | grep uvcv and you'll get the module name.
This will disable it for this session.
To make it permanent, add
blacklist + module name to
Another foolproof solution that wouldn't work for everyone:
Open the laptop up, and unplug the webcam. Use an external webcam instead, pluggin it in only as required. I actually did this in the opposite order as the internal webcam was poor quality and I didn't want it on the same angle as the screen.
