Record screen, microphone and web camera in Ubuntu 17.10 (Wayland Session)
Solution 1:
If you're really inclined to further use Wayland you should give green-recorder a try.
It even is able to record games you play, only caveat is that it only records as WebM format under Wayland. Have to mention that it only records the screen, not a webcam for example.
To install it you need to add a new ppa into your system, so you can follow the steps below to install it from terminal command line.
sudo add-apt-repository ppa:fossproject/ppa
sudo apt update
sudo apt install green-recorder
To add to this you might want to install TopIcons plus extension from extensions.gnome.org to be able to access green-recorder when it has started recording.
The only other chance you have to get the software you mentioned to work again is starting your desktop under Xorg as display-manager.
To do so you have to log out and use the cogwheel beside the sign in button to choose 'Ubuntu on Xorg'.
An other possibility to just create a smaller screen-cast of about 30 seconds would be to just press shift+ctrl+alt+r this will leave the recorded bit in your 'Video' directory in your home (/home/$USER/Video/
). Thus this solution does not seem to work under Xorg and producing files of 0 Byte length.
