Congratulations you just finished your Ubuntu 15.04 installation. Here is top things you should do after install Ubuntu 15.04.

1. Update Your System

Altough you are using the latest version of Ubuntu, the software package is not always the latest version. You need to (as soon as posible) update your system. You can do it with simple command line: [sourcecode] sudo apt-get update && sudo apt-get upgrade [/sourcecode]

1. Install Restricted Driver

You can pass this step if you're really the hardcore FOSS evangelist. We need some restricted driver that can't be shipped by default to Ubuntu ISO. You can do it with this command: [sourcecode] sudo apt-get install ubuntu-restricted-extras ubuntu-restricted-addons [/sourcecode]

1. Activate Additional Driver

Do it when you are using fancy GPU like NVIDIA or ATI. Type "Additional Driver" in Ubuntu Dash (Win Key). Run the "Additional Driver" apps.

1. Install Ubuntu DConf Editor

You need Dconf Editor to deeply customize your Ubuntu system. So install it with: [sourcecode] sudo apt-get install dconf-editor [/sourcecode]

1. Disable Global Menu

I hate using Global Menu when using this Ubuntu on Big screen. You can disable the global "mac os x-like" menu with Go to System Settings > Appearance > Behavior and choose the desired location of menus from ‘Show the menus for a window‘ option.

1. Disable Auto-hide Menu

Using Dconf Editor, go to com > canonical > unity. There you have to check the ‘always-show-menu’ option. Now you have menus showing all the time, no more guess work.

1. Disable Online Search

Go to System Settings > Security & Privacy > Search and slide the button to off position.

1. Install Y PPA Manager

Do PPA management easly with Y PPA Manager. Install with this command: [sourcecode] sudo add-apt-repository ppa:webupd8team/y-ppa-manager && sudo apt-get udpate && sudo apt-get install y-ppa-manager [/sourcecode]

1. Install Another Software Center, Deepin Software Center [sourcecode] sudo add-apt-repository ppa:noobslab/deepin-sc sudo apt-get update sudo apt-get install deepin-software-center-2 [/sourcecode]

2. Install GDebi (DEB Package Installer)

[sourcecode] sudo apt-get install gdebi [/sourcecode]

1. Install VLC, Google Chrome, Clementine

[sourcecode] sudo apt-get install vlc google-chrome clementine [/sourcecode]
