Although if you use Ubuntu, then yet it doesn't come with a one pre-installed (it probably never will since screen recorder is not something that not everyone will use) but I'm pretty sure there are a lot you can find.
But if you've been looking for a very simple screen recorder that does nothing else (you know, without advanced video editing, cropping, etc) then Kazam is an excellent little tool.
*. It's written in the GTK+ tool kit and uses the ffmpeg multimedia library for the recordings.
*. You can record both video (from your Computer screen of course) + an audio channel if you wanna add a voice as well.
*. Once you push the "Record" button it'll start to record whatever is on your desktop screen and you can use it's icon that runs in the notification area to Pause or Stop the recording.
*. As said, it doesn't have a video editing function (other than a basic one, more below) but since Ubuntu come with a pretty good one called Pitivi, Kazam will ask you to whether you wanna edit the video using Pitivity or just save it to disk.
|You can directly open the recorded video in PiTiVi...|
*. Saves the recorded multimedia file in .MKV container format.
You can install Kazam in Ubuntu 11.04 Natty Narwhal, 10.10 and 10.04 by using the daily unstable PPA channel (the stable channels doesn't have packages for Ubuntu 11.04) + 11.10 is not yet added. Open your terminal window and enter the below commands.
