Gnome: How to record a screencast

Gnome 3 has in-built screencast functionality. To start record your screen simply press

Ctrl + Shift + Alt + R

The indicator (a red circle) will appear in the panel, informing you that the recording has started. Default video length is limited to 30s, what might be not enough in most cases. To adjust this parameter install dconf Editor and go to the:

org.gnome.settings-daemon.plugins.media-keys

And look for max-screencast-length to adjust.
