= Desktop Add-ons =
There are many add-on icons, themes, wallpapers, 3-D effects, and other customizations available for the GNOME desktop.

=== Gnome Eye-Candy Resources ===
* [http://www.gnome-look.org Gnome Look] has wallpapers, splash screens, icons, and themes for windows managers (including Metacity and Compiz) and other applications.

=== Ubuntu Wallpaper ===
*Download free [https://wiki.ubuntu.com/Artwork/Incoming/Lucid Lucid Lynx wallpapers].

=== Change Plymouth Splash Screen ===
This is the initial splash screen you see at bootup. Different Plymouth themes can be found by searching for plymouth-theme in a Package Manager. Install a new one and then:
 sudo update-alternatives --config default.plymouth
 sudo update-initramfs -u

:and manually select the theme you wish to use.

Plymouth does not reliably work with nVidia drivers and during bootup a blank screen may result for several seconds.
<!--->
=== Change USplash Boot Screen ===
This is the splash screen you see at bootup, when you are asked for a login and password. You can change the USplash screen using the utility startupmanager. (Startup Manager can also be used to change GRUB bootup settings if you use multiple OS's on your computer). Install:
 sudo apt-get install startupmanager
:Start:
System -> Administration -> Startup Manager

You could alternatively use a different splashscreen manager, [http://ubuntuforums.org/showthread.php?p=3440101#post3440101 Splashy], instead of USplash. Install:
 sudo apt-get install splashy splashy-themes<--->

=== Metacity ===
Metacity is the default desktop compositing manager in Gnome. It is lightweight, streamlined and does not have many configurable options, but has multiple themes available at Gnome Look.

=== Compiz Fusion ===
Compiz Fusion is available as a separate Windows Manager, to allow advanced desktop effects such as the rotating cube desktop. Many Ubuntu users choose to run Compiz, which is quite fast in Ubuntu. Install:
 sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-main compiz-fusion-plugins-extra emerald librsvg2-common

To change to Compiz as the Window Manager:

*Select Compiz Configuration:
:System -> Preferences -> CompizConfig Settings Manager

:Note: You must logout and log back in for the change to take effect.

==== Fusion Icon ====
Fusion Icon is a tray icon that allows you to easily switch between window managers, window decorators, and gives you quick access to the Compiz Settings Manager. This allows quick toggling of 3-D desktop effects (that may not be compatible with some applications).
 sudo apt-get install fusion-icon

:Applications -> System Tools -> Compiz Fusion Icon

You can then easily access CompizConfig Settings Manager from the icon.

==== Rotate the Compiz Cube ====
Set the CompizConfig Settings Manager to enable the "Desktop Cube" and "Rotate Cube" and "Viewport Switcher" options. Click on the icon for each to customize settings. For example, to change the appearance of the cube, click on the Desktop Cube icon to access its settings. You can set the hotkey buttons for rotating the cube in the "Viewport Switcher" settings. Otherwise, hold down the Ctrl+Alt+Left mouse button and drag the mouse (or touchpad) the direction you want to rotate the cube.

Remember, the cube rotates between desktops. It's not a cube unless you have at least 4 desktops running. You will not get a cube if you are only using 2 desktops (you will get a "plate"). You can still rotate the sides of the plate, of course, but it will not be a cube. (Recent users from the Windows OS may have no experience with the concept of simultaneous desktops, but they are nice once you learn how to use them).

When running Compiz fusion as the Windows Manager, you must change the default number of desktops from within CompizConfig Settings Manger. To enable 4 desktops:
:CompizConfig Settings Manager -> General -> General Options -> Desktop Size -> Horizontal Virtual Size -> 4

When you start an application, you can assign it to any one of the 4 desktops by right-clicking the upper left corner of the application window and choosing the "To Desktop..." option. Rotating the cube shows the different desktops. You can also go to a desktop using the taskbar icon which shows the 4 desktops.

==== Emerald ====
Emerald is the theme engine for Compiz Fusion.  Multiple themes are available. (These themes originated from the Beryl project before it merged with Compiz to form Compiz Fusion.)
The Emerald Theme Manager for Compiz Fusion can be installed:
 sudo apt-get install emerald

=== Google Desktop ===
[http://desktop.google.com/linux/index.html Google Desktop for Linux] is a proprietary suite of widgets and applications to give Google control over your computer and thereby allow you to use Google services. A .deb package can be downloaded and installed from [http://desktop.google.com/en/linux/download.html Google Linux Downloads]. For installation instructions, see [http://desktop.google.com/support/linux/bin/topic.py?topic=11377 Google Desktop for Linux Instructions].

=== gDesklets ===
[http://www.gdesklets.de/ gDesklets] are similar to Windows widgets and Google gadgets and provide information such as weather, system resources, and news. For more information refer to this [http://www.howtoforge.com/gnome_gdesklets gdesklet installation tutorial]. Install:
 sudo apt-get install gdesklets

== Dock applications ==
Avant Window Manager, Cairo Dock, gnome-do and Wbar are dock-like applications for Ubuntu Linux. A dock represents running programs as icons at the bottom of the screen (as is done on the Mac OS X desktop), instead of by toolbar panel segments (as is done in Windows and other Linux window managers). See this [http://linuxowns.wordpress.com/2008/05/08/the-best-and-worst-docks-for-ubuntu/ brief comparison of dock applications].

=== Avant Window Navigator ===
*[http://wiki.awn-project.org/ Avant Window Navigator] requires that a desktop composition manager (such as Metacity, Compiz, Xcompmgr, KDE4 (Kubuntu), or xfwm4 (Xubuntu)) be installed and running.
*Install and upgrade proprietary nVidia or ATI graphics drivers so that the compositing manager functions properly.
*Install AWN:
 sudo apt-get install avant-window-navigator awn-manager

:(Note: If you are using Gnome (Ubuntu) and do not already have a compositing manager installed (such as Compiz), Metacity will be installed as part of the installation.)

*Enable automatic startup of AWN at bootup:
:*Menu -> System -> Preferences -> Startup Applications -> Add...
 avant-window-navigator

*Select which applets should run from the dock menu by default:
:*Menu -> Applications -> Accessories -> Avant Window Navigator Manager
:You can drag application icons onto the list, then activate or deactivate the applets from the list.

=== Cairo Dock ===
[http://developer.berlios.de/projects/cairo-dock/ Cairo Dock] can be used either with a desktop compositing manager (such as Metacity for Gnome, Compiz, or the KDE4 Window Manager) or without one. See [https://help.ubuntu.com/community/CairoDock the Ubuntu installation instructions] for details. It is available from the repositories:
 sudo apt-get install cairo-dock cairo-dock-plug-ins

=== Gnome Do ===
[http://do.davebsd.com/ Gnome Do] is a docking utility for Gnome. Install:
 sudo apt-get install gnome-do

*From the preferences pane of gnome-do select the Docky look and feel to get the dock (rather than the default Quicksilver-like) look and feel.

=== wbar ===
[http://code.google.com/p/wbar/ wbar] is a quick-launch bar (not a dock) that has an appearance similar to Avant Window Manager and Cairo Dock. It is GTK (Gnome) based but can work in all desktop environments. It does not require a compositing manager to be installed and is therefore quicker and more suitable for low-end hardware systems. It is the default in the Google gOS desktop and is available as a .deb package from Google. Download and install (from the command-line Terminal):
 wget <nowiki>http://wbar.googlecode.com/files/wbar_1.3.3_i386.deb</nowiki> 
 sudo dpkg -i wbar_1.3.3_i386.deb

*Start wbar with custom start options (e.g. by pressing alt+F2). Here is an example:
 wbar -isize 48 -j 1 -p bottom -balfa 40 -bpress -nanim 3 -z 2.5 -above-desk

:Here is another example:
 wbar -above-desk -pos bottom -isize 60 -nanim 1 -bpress -jumpf 0.0 -zoomf 1.5

For a full list of command-line startup options, see:
 wbar --help

Tip: If you want the "wave" effect just increase the -nanim value. I like the icons to just pop up so I don't use it, but with 9 icons 5 there is a nice "wave" effect.

Obviously, you could create a menu item with the command line options (similar to the examples above), or a batch file that can be automatically started at system startup (as a cron event or startup session).

You can also change wbar startup options by editing the configuration file:
 sudo gedit /usr/share/wbar/dot.wbar

See [http://ubuntuforums.org/showthread.php?t=980565 this example configuration file]. However, not all options are able to be set from the configuration file and must be run from the command line. For more info see [http://linux-guider.blogspot.com/2008/09/wbar-another-cute-dock.html this wbar guide].

==== wbarconf ====

A simple [http://www.gnomefiles.org/app.php/wbarconf wbar configuration utility] can be downloaded as a .deb package and installed:
 wget <nowiki>http://koti.kapsi.fi/~ighea/wbarconf/wbarconf_0.7.2-1_i386.deb</nowiki>
 sudo dpkg -i wbarconf_0.7.2-1_i386.deb
