This quick tutorial is going to show beginners how to disable your laptop camera in Ubuntu Linux.
You may ask why? Just in case, right?
To get started, press Ctrl+Alt+T on keyboard to open a terminal. When it opens, run this command to edit the config file:
sudo gedit /etc/modprobe.d/blacklist.conf
When the file opens, add a new line into the end which will prevent the camera module from loading when Ubuntu boots up.
Finally save the file and restart your computer to apply the changes.
