Things To Do After Installing Ubuntu 12.04 'Precise Pangolin'

Ubuntu 12.04 final has been released. Check out our post installation guide for Precise.

Ubuntu 12.04 installer allows you to install updates and refresh repositories from installer itself, if you are connected to the Internet. If you skip this part, later you should update your system and repositories. To do that, just launch update manager from dash menu. If you want to have faster updates, select a server near you or start the test which will automatically set a best server for you.

Go to additional drivers and install new drivers as required.

Install Ubuntu Restricted Extras from Ubuntu Software Center to add support for flash, java and mp3 playback. If you already installed updates and third party software during installation, you can skip this step.

Add support for encrypted DVD by running following commands:

sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh

If you want to add support for Systray or Notification Area which has been disabled in Unity, install and launch dconf-editor from Ubuntu Software Center. Now to enable it just add an extra string 'all' under Desktop > Unity > Panel as shown in screenshot below (requires a logout to work). To revert, just click on 'Set to Default'.

Install your favorite indicators. A list of indicators with installation instructions can be found on Ask Ubuntu and here.

Though Ubuntu 12.04 comes with quicklists for most of the apps, you can add custom quicklists support to your favorite apps. Many quicklists and their installation instructions can be found here.

Change Unity launcher behavior and control what shows in dash by going to privacy settings in system settings.

In case you are only able to access Unity 2D, run the command below to check if your system supports Unity 3D.

/usr/lib/nux/unity_support_test -p

Medibuntu (Multimedia, Entertainment & Distractions In Ubuntu) is a repository of packages that cannot be included into the Ubuntu distribution for legal reasons (copyright, license, patent, etc). You can add Medibuntu repository by running commands below:

sudo -E wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update

sudo apt-get install app-install-data-medibuntu apport-hooks-medibuntu

You can install new Gnome 3.4 apps in Ubuntu without installing Gnome Shell by running command below. These applications lack proper Unity Integration though.

sudo apt-get install epiphany-browser gnome-documents gnome-contacts

To install latest Gnome Shell 3.4, run the command:

sudo apt-get install gnome-shell

Not all gnome 3.4 components have been updated in Precise. Run the commands below to fully update all your Gnome 3.4 components. Beware that these packages may break your system.

sudo add-apt-repository ppa:ricotz/testing 
sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update && sudo apt-get upgrade

To install classic two panel Gnome session, run the command:

sudo apt-get install gnome-session-fallback

If you want to try new Linux Mint Cinnamon interface, run the commands below:

sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
