GNOME

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

GNOME 3

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:

• Frippery Move Clock - moves the clock to the right instead of in the middle
• Alternative Status Menu - puts power-off/restart back into the menu
• Window Overlay Icons - adds icons to the window list
• Weather - at last the old Gnome2 whether is available for Gnome 3!
• Bitcoin Price - my first Gnome extension which adds the current Bitcoin price to the main panel

Writing extensions

• Good example of creating extension prefs

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.
