This post follows my previous where I blogged on replicating an ubuntu repo locally. As I had a few stations to install using the same method everytime, I have decided to document the setup to 12.04 LTS.

First things first, disabling Unity and reverting to Gnome Classic (log out then select gnome-classic from the login menu):

apt-get install aptitude
aptitude install gnome-session-fallback
/usr/lib/lightdm/lightdm-set-defaults -s gnome-classic

The next thing I got to do is installing all the restricted codecs to make the station usable with all the junk on the internet:

apt-get install ubuntu-restricted-extras ubuntu-restricted-addons

Next is to install libdvdcss so it can read encrypted DVDs. I usually install the medibuntu repos. Then the package:

sudo 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
apt-get install libdvdcss2

If you are looking for more, I would advise a stop by this blog.
