Recording your screen on Linux OS has never been easier, but it can be a little tricky since most Linux Distros don’t have it out-of-box.
In order to record your screen, you’ll need to install an external software/application.
However, in the case that your OS has the Gnome 3 Desktop Environment, you can now record your screen with just a combination of keys.
Gnome is a free, open-source desktop environment for most Linux and GNU OS, like Ubuntu and Fedora.
With Gnome 3, you don’t need to install any external software for screen recording.
To start recording your screen, all you need to do is press the keyword combination Ctrl+Shift+Alt+R. You should see a tiny red/orange circle at the top right corner that indicates it’s recording your screen.
To stop recording your screen, repress the same key combination. That’s all.
Mind you; this feature stops recording your screen once it reaches the maximum duration set. The good thing is that this duration can be changed using the command line.
Open your command line and enter the command below to get the current set duration (it’s usually 30 seconds by default):
$ gsettings get org.gnome.settings-daemon.plugins.media-keys max-screencast-length unit32 30
To change the duration, you can use the command below:
$ gsettings set org.gnome.settings-daemon.plugins.media-keys max-screencast-length 120
That’s all. You can rerun the first command to verify if the duration changed.
