Best Screencasting Software for Ubuntu 11.10/12.04

For Ubuntu 11.10 (Oneiric Ocelot) or 12.04 (Precise Pangolin, right now, only alpha version is available) LTS there are lot of ways to record desktop – to create screencast. Some of the most popular applications include – xvidcap, Tibesti, RecordMyDesktop, Kazam etc. Screencasting has become a very popular medium for delivering tutorials, so it must record screen without any lagging or distortion, and of course the HD quality should be supported. In this post I’ve described two popular tools – out of which first one is only for Gnome Shell users while second one will work with most of the Gnu/Linux distributions.

Recording Screen in Gnome Shell Desktop

Recording Screencast in Gnome Shell

If you’re using Gnome Shell Desktop rather then the default one which is unity, then you can start capturing your screen without any extra software – because it’s a built in feature.

Just hit Ctrl+Shift+Alt+r and start capturing your screen. You will notice an indicating red dot in bottom right corner. To stop recording, press the same keys again. The output file will be saved in ~/shell-*.webm , but there is one problem! it won’t record any audio. But you can fix that by recording the voice simultaneously using Sound Recorder (installed by default) and finally merge he Audio and captured screen video using OpenShot (or any other video editor of your choice).

recordMyDesktop – Best Screencasting Application for Ubuntu


recordMyDesktop (or Desktop Recorder) is a simple and easy to use screencasting software for Ubuntu or other GNU/Linux distributions which are based on Gnome or KDE desktop. The core program is written in C language – it’s a command line tool for recording screen, while the UI has been implemented in two ways – One Python based (pyGTK) for Gnome users while other one is Qt (pyQt4) based for KDE desktop users.

Encoding Process after Screencasting

recordMyDesktop is a free software and uses only open formats such as ogg for audio and theora for video. It has a lot of features and options to customize the recording and other settings, and of course it also records audio. If it’s not recording audio properly then go to Sound Settings and correct the input device settings for audio recording. The user interface seems little confusing (you may need to provide the save as location and file name first before starting recording process) but it works fine.

How to install recordMyDesktop in Ubuntu 11.10/12.04

Fire up a terminal (Ctrl+Alt+t) and execute the command (or search in Software Center) –

sudo apt-get install gtk-recordmydesktop

Update 1. Added Eidete

Eidete : Another Great Application for Screencasting on Ubuntu

If recordMyDesktop doesn’t work for you, then you may want to try Eidete. It’s a very simple application but it works great (I’ve tried in Ubuntu 12.04). It has some awesome features like – tracking mouse clicks, colored circle for mouse movements etc.


Install Eidete in Ubuntu

First, you need to add the PPA for Eidete, then update the repository and install it. So, open a terminal and execute –

sudo add-apt-repository ppa:shnatsel/eidete-daily
sudo apt-get update
sudo apt-get install eidete

Update #2

Here is another one (probably the best) : SimpleScreenRecorder. It has simple and easy to use UI and lots of features to control the quality and recording experience. In my experience, it’s the best one.

Install SSR in Ubuntu

sudo add-apt-repository ppa:maarten-baert/simplescreenrecorder
sudo apt-get update
sudo apt-get install simplescreenrecorder

How to install Mac OS X Lion Theme in Ubuntu 11.10/12.04

In earlier versions of Ubuntu, actually up to 10.10, a Mac OS X transformation pack was available for Ubuntu users (based on GTK 2.*) but now the Ubuntu 11.10 (the latest stable version) or 12.04 LTS (only alpha versions are available right now) as well as other Ubuntu derivatives such as Linux Mint, are based on GTK 3 – so the transformation pack doesn’t work anymore. Both of the desktop – Unity (The default interface in 11.10) and Gnome 3 shell are quite popular. I’ve already covered a post about getting a Mac like look in Ubuntu 11.10 with Gnome shell desktop so this article is about Unity desktop.



If you want to make Ubuntu 11.10/12.04 look like Mac OS X Lion, then you need to install few basic things –

  1. GTK Theme
  2. Icon Theme
  3. Cursor Theme
  4. Gnome Tweak Tool (To manage themes)
  5. A dock application (Docky or Cairo Dock)

A cool snapshot – exploring Cairo Dock effects (using OpenGL, although you may choose to ‘no OpenGL’ version of Cairo Dock if the graphics performance of your computer is poor), of  my desktop after install above stuffs :

mac osx-theme-in-unity


Installing Mac Theme by ‘MBoss’ Packages

First of all – download the theme package (it contains theme, icons and cursors) and extract it to appropriate locations as specified –

1. Download Mac OS X GTK Theme package and extract it to ~/.themes

2. Download the Mac OS X Icon theme and extract it to ~/.icons       (create that directory if it doesn’t exist)

3. Download Mac OS X Cursor Icon theme and extract it to /usr/share/icons

For extracting cursor icons to usr/share/icons location, you need root access while browsing with nautilus

gksu nautilus

and finally you may need to change the permission settings to make it accessible also by a non root user. (By default it may be assigned root permission only).

Change Directory Permissions

Install Docky or Cairo

If you like Docky then install it from Ubuntu Software Center or execute (as it’s there in repository by default) –

sudo apt-get install docky

On the other hand – if you want to try Cairo Dock (as seen in screenshot) then execute these commands

sudo add-apt-repository ppa:cairo-dock-team/ppa
sudo apt-get update
sudo apt-get install cairo-dock cairo-dock-plug-ins

Gnome Tweak Tool is very handy for changing themes or tweaking other settings of Desktop so If you haven’t already installed it Gnome Tweak Tool then install it by executing the command –

sudo apt-get install gnome-tweak-tool


Now, open Gnome Tweak Tool and select Mac_OS_X_Lion_Theme  – as indicated in above snapshot. Then, start Cairo Dock or Docky whatever you have installed. That’s all I hope you are enjoying the cool look of Mac on your Ubuntu 11.10/12.04 computer. Have Fun :) – let me know if any problem occurs.

Besides Gnome Tweak Tool, you could also use ‘Ubuntu Tweak‘ – a small application to tweak/customize desktop in easy way.

ubuntu Tweak

To install Ubuntu Tweak, execute the following commands –

sudo add-apt-repository ppa:tualatrix/next
sudo apt-get update
sudo apt-get install ubuntu-tweak

Thanks to MBOSSG for his art work – i.e Mac OS X Theme, icons and cursor themes.
