Recently, when I wanted to create a video demonstration which involves recording my computer screen and the input from my microphone. As an Ubuntu GNU/Linux user, I've tried few different screen recorder software but, the results were not very encouraging. However, in my recent attempt, I found a nice piece of software which could meet my requirements. It's called Kazam screencaster program. I just thought to leave a note about it here so that I can find it when I need it the next time.
It is available on the Ubuntu software repositories and we can install it with the following command.
sudo apt update
sudo apt install kazam
