GNOME offers an easy to understand desktop environment for your GNU/Linux or UNIX computer.

Extensions

The GNOME Shell extension design is designed to give a high degree of power to the parts of the GNOME interface managed by the shell, such as window management and application launching. It simply loads arbitrary JavaScript and CSS. This gives developers a way to make many kinds of changes and share those changes with others, without having to patch the original source code and recompile it, and somehow distribute the patched code.

Extensions are listed at extensions.gnome.org and can be installed one-click style directly from the site :-) some extensions that I recommend are:

Writing extensions

Create an initial working extension template using the gnome-shell-extension-tool --create-extension command, then after you change your code, you restart the Gnome shell by pressing ALT+F2, then entering r and pressing Enter. To check for errors and perform other debugging tasks, use the LookingGlass applet which can be started by pressing ALT+F2, then entering lg and pressing Enter, the escape to close it.

Installing on Ubuntu 12

They've now made Unity the default desktop environment which many people find really horrible, to install GNOME do the following:

<bash>sudo add-apt-repository ppa:gnome3-team/gnome3

sudo apt-get update sudo apt-get install gnome-shell</bash>

Then log out and select GNOME at the login prompt

Adding your own apps to the search

You'll need to create a .desktop file for your application in the ~/.local/share/applications directory with the name of your application as its filename. The content of the file is of the following format:

[Desktop Entry]
Name=My applications name
Comment=My cool application
Exec=/full/path/to/my/app
Icon=/full/path/to/my/app/icon
Terminal=false
Type=Application
StartupNotify=true

Where'd the startup applications applet go?

It's still the same program which is gnome-session-properties, but for some reason there's no longer a launcher for it - you can make one using the instructions in the previous section if you like, or launch it manually from a terminal window.
