2) Changing your theme
Ubuntu’s default theme is good and enough for me because i’m using morethen 5 years and i’m not feeling even a sec for changing theme but others wont feel like me. If so, you can change the theme to make your Desktop as your wish. You can done this by navigating System Settings –> Appearance. If you are not feeling this is enough for you, you can install more themes also. Install Unity Tweak Tool for more customizable features.
# unity tweak tool installation # [email protected] [~]$ sudo apt-get install unity-tweak-tool
