I am trying to do screen recording on Ubuntu 12.04 LTS and supposedly pressing Ctrl+Alt+Shift+r will do it.
In order to get audio I found on a different post that I need to run the command:
gsettings set org.gnome.shell.recorder pipeline "queue ! videorate ! vp8enc quality=10 speed=2 ! mux. pulsesrc ! audio/x-raw-int ! queue ! audioconvert ! vorbisenc ! mux. webmmux name=mux"
However when I run this I get
No such schema org.gnome.shell.recorder.
How can I fix this? Do I need to install the schema somehow? I have been unable to find anything on this.
