5 important things after Installing Ubuntu

When first installing Linux, especially Ubuntu family and its variants, the first thing to do is:

1. Creating a root account
Go to Terminal (Application > Accessories > Terminal) then type

sudo passwd root

and enter your password and root password 2 times, for Authentication.
* when typing a password in a terminal, characters are not visible for security reasons.

2. Change the default download to a local repo
go to System> Administration> Software Sources.
then enter your password and look under the Ubuntu Software tab, then select "Download from:" select "Other" and select the server that you want.
when you're finished, click "Choose Server" and Reload, then the database retrieval process will take place
* Internet connection required

in this example, we use VirtualBox with Ubuntu 9.04 OS and download the server from the center, because the local repo is down.
if the database update process is complete, now we will add the source partner, and it's still locked.
go to Terminal and run
sudo gedit /etc/apt/sources.list

then remove the # before deb word, so it looks like this
[...]
## Uncomment the following two lines to add software from Canonical's
## 'partner' repository.
## This software is not part of Ubuntu, but is offered by Canonical and the
## respective vendors as a service to Ubuntu users.
deb http://archive.canonical.com/ubuntu jaunty partner
deb-src http://archive.canonical.com/ubuntu jaunty partner
[...]

Save & close the file and do not run sudo apt-get update.
Hint
Jaunty is the code name for Ubuntu 9.04. for another version of ubuntu, you just replace the Jaunty with:
karmic = 9:10
Lucid = 10:04
maverick = 10:10

3. Adding Medibuntu Repo
Go to Terminal dan run
sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list --output-document=/etc/apt/sources.list.d/medibuntu.list
then import gpg-key and update the database
sudo aptitude update && sudo aptitude install medibuntu-keyring && sudo aptitude update

sudo update-apt-xapian-index
Medibuntu repo now already in the synaptic list.
then we update our system to be able to go to the next step

sudo aptitude safe-upgrade

press Y to confirm the installation.

4. Installing multiple applications and codecs
before doing anything, we separate between the Codec with supporting applications.
how to install it, can be found on the Ubuntu Software Center or install via terminal by typing

sudo apt-get install packet_name

Codecs & Multimedia Plugin: (mandatory if you want to enjoy multimedia content in comfort)

* ubuntu-restricted-extras
* msttcorefonts
* flashplugin-nonfree
* non-free-codecs
* libdvdcss2
* gstreamer
* sun-java6

Application Support: (Optional, up to you want to install or not)
"scribus" = Alternative to Adobe InDesign in Linux
"vlc" = Movie Player is quite light and have a lot of plugins
"audacity" = Music Player is lightweight and has a lot of plugins
"bluefish" = Text Editor is quite complete, almost like Notepad + +
"thunderbird" = e-mail client, fitting for Gmail users because it is easy settings
"Kompozer" = HTML editor, similar to MS Frontpage

5. Changing Theme and enhance your desktop

At this stage, I believe the system has been updated with better, but still the view that it is only
if you get bored with the usual display, you can look for themes to change your desktop to look like a Mac, Windows, or actually be different from the other OS

For how to enhance the desktop, you can see the tutorial in this forum http://kask.us/5091758.
