Introduction

Cairo-Dock is an animated application launch bar for the desktop, comparable to the dock in Mac OS X or Rocket Dock (for Windows). Now, you can use Cairo-Dock with OpenGL (to use your graphic card!). You can find some screenshots here.

Since Cairo-Dock 2.4 (by default on Ubuntu 11.10 Oneiric), it’s possible to launch a Cairo-Dock session: it will launch a Gnome session with Compiz (or Metacity) without any panel/dash except Cairo-Dock. But Cairo-Dock is compatible with most WMs (Compiz-Fusion, Beryl, Compiz, Metacity, Kwin, etc.), most environments (Gnome, XFCE, LXDE, KDE, etc.), most sessions/panels/dashes (Unity, Gnome-Shell, XFCE panel, LXDE panel, KDE panel, etc.). It’s better with a composite manager (if your WM doesn’t support the compositing — e.g. if you’re a black/non transparent background — simply install Compton or Xcompmgr), but it can also use fake transparency.

This page only describes how to install Cairo-Dock and some basic usage instructions. If you want to know more about configuration and themes you should go to the Cairo-Dock website, its wiki and read this tutorial. The site is in French and in English, the wiki has a complete English section and don’t be afraid to ask questions or report bugs in the forum.

Installation

The project is split into two parts: the dock itself and the plug-ins. Only the installation of the dock is explained, but installing the plug-ins is the same, just make sure you install the plug-ins after the dock.

The config file will not be overwritten during updates as Cairo-Dock is capable of inserting the missing fields if any without losing your previous settings.

Please note that, although Cairo-Dock is listed in the Universe repository since Ubuntu 8.10 (Intrepid Ibex) and can be installed using Synaptic Package Manager, but it is recommended to install Cairo-Dock using one of the methods described below to get the most up-to-date and stable version of Cairo-Dock.

From the Repository/PPA (Stable)

Cairo-Dock devs maintain their own repository and a PPA for all supported versions of Ubuntu.

PPA

Simply launch these commands from a terminal:

sudo add-apt-repository ppa:cairo-dock-team/ppa sudo apt-get update

If Cairo-Dock is already installed, install the updates by using the Update Manager or this command:

If not, install it via the Software Center or via this command:

sudo apt-get install cairo-dock cairo-dock-plug-ins

Cairo-Dock repository

To add the Cairo-Dock repository to your sources simply launch these commands from a terminal:

echo "deb http://download.tuxfamily.org/glxdock/repository/ubuntu $(lsb_release -sc) cairo-dock ## Cairo-Dock-Stable" | sudo tee -a /etc/apt/sources.list wget -q http://download.tuxfamily.org/glxdock/repository/cairo-dock.gpg -O- | sudo apt-key add - sudo apt-get update sudo apt-get install cairo-dock cairo-dock-plug-ins # OR if it's already installed => # sudo apt-get dist-upgrade

Development version: PPA (can be unstable)

A PPA is regularly updated. You can add it and install the latest version of Cairo-Dock with these commands launched from a terminal:

sudo add-apt-repository ppa:cairo-dock-team/weekly sudo apt-get update >/dev/null sudo apt-get dist-upgrade

Development version: Compilation (can be unstable)

A script has been written to compile the BZR version of Cairo-Dock easily. So, you just have to create a directory where the script will be installed in, download the script and launch it:

Open a terminal, and create a new directory:

mkdir /cairo-dock_bzr cd /cairo-dock_bzr

Then get the script, make it executable and launch it:

wget http://bzr.glx-dock.org/cairo-dock_bzr.sh chmod u+x cairo-dock_bzr.sh ./cairo-dock_bzr.sh

Simply follow the instructions (in English)

To finish, enter your own password when prompted by the script in order to proceed with to the installation.

A line will appear after the installation of each module and a final message will appear indicating that everything went well. If not, consult the log.txt file in the directory you have created at the beginning. Look at the end to locate the problem, then post it in the forum.

What is installed?

Cairo-Dock stores your launchers and your parameters in a hidden directory, ~/.config/cairo-dock

Also, binaries are in /usr/bin and data (including the default themes) in /usr/share

First Launch

If you installed Cairo-Dock from the packages, you can logout to launch the new Cairo-Dock session or if you want to use it on your current session, there should be a launcher in the applications menu, under the System Tools sub-menu. If there isn’t a launcher there, just press Alt+F2 and type in cairo-dock. To enable backtraces on launch (sometimes useful if a problem occurs), open a terminal and type cairo-dock & disown and press enter.

On first launch, Cairo-Dock will configure itself and will offer you a list of themes to choose from. This allows you to have a fully functional dock immediately. You will have to move the mouse cursor to the bottom of the screen to see the dock if auto-hide has been enabled. This depends on the theme you chose at launch.

If you want to use another theme, right click on the dock and select Cairo-Dock > Configure > Themes. To configure the dock’s settings, right click the dock and select Cairo-Dock > Configure.

REM: Cairo-Dock has a support of OpenGL. If you want to use it automatically, simply launch Cairo-Dock with cairo-dock -o. Note that the OpenGL can be badly supported by your video drivers but most of them support it well (have a look the wiki of Cairo-Dock for more details).

Cairo-Dock

Cairo-Dock is a highly customizable dock written in C.

Installation

The core package provides only the strict minimum to run Cairo-Dock — to use applets, animations, views, effects and dialogs you will also need cairo-dock-plug-ins .

Plugin dependencies

The applets in cairo-dock-plug-ins require quite a lot of dependencies, therefore all of them have been made optional not to bloat your system if you do not use a particular applet. Please refer to the optdepends list and install those you need.

Note: If for some reason an applet is not working, make sure you have GVFS installed, it is required for several applets as well as GNOME, XFCE and KDE integration.

Configuration

Running the dock

Run the dock in the background:

This will generate a startup message that will ask you to choose a backend for the current session (OpenGL or Cairo). There is an option to remember the choice and if not choosing to remember the choice, a startup message will be generated each time Cairo-Dock is run without backend options. To supress the startup message, you can specify which backend to use when running Cairo-Dock by specifying it as an option.

Run the dock with OpenGL backend:

Run the dock with Cairo backend:

Tip: All using ATI graphics cards should use this option. Some cards/drivers do not support OpenGL, which may prevent Cairo-Dock from running correctly.

Running the dock at startup

This depends on which desktop environment or window manager that is being used and which backend Cairo-Dock should be run with. The following section shows how to run Cairo-Dock at startup without forcing a backend.

Cairo-Dock method

Run Cairo-Dock and right-click the dock and go to Cairo-Dock > Launch Cairo-Dock on startup. The settings will be stored in ~/.config/autostart/ and sourced the next time you login.

Openbox/Fluxbox

Add the following to ~/.config/openbox/autostart or ~/.fluxbox/startup accordingly:

Xfce

If you have xfce4-autostart-editor installed, simply run it and add an entry for Cairo-Dock. If you are not using a session manager you can add the following to ~/.config/xfce4/xinitrc or ~/Desktop/Autostart :

GNOME

Add a Cairo-Dock entry to Startup Programs using

Configuring the dock

To configure the dock, right-click the dock and go to Cairo-Dock > Configure.

Troubleshooting

Two Cairo-Docks are running

This is most likely a result of saved sessions being runned at login. If you are using a desktop environment like GNOME, KDE or Xfce you need to disable automatic startup of sessions in your session manager settings. You may also need to delete the sessions cache:

If you are not using a desktop environment with a session manager or choose to have Cairo-Dock startup by itself, you need to remove autostart files generated by Cairo-Dock:

$ rm ~/.config/autostart/cairo-dock*

The background is black

This is most likely caused by not running a composite manager, like Xcompmgr. Cairo-Dock uses the transparency feature of the composite manager to display the dock, and without it the dock will be displayed with a black background. If you are using a desktop environment, simply enable the composite manager or desktop effects in the settings.

An alternative solution that does not require a composite manager is to enable fake transparency in Cairo-Dock. To do this, right-click the dock and go to Cairo-Dock > Configure > Advanced Mode > System > Composition. Then enable both Emulate composition with fake transparency and Make the config panel transparent.

Wifi plugin does not show the network strength

If you added the wifi plugin, and it is not showing the network strength, you have to certify that you have iwconfig installed (the plugin depends on it) and that you have permission to read the full output of iwconfig.

And to get the permission to read the full output of the iwconfig as a normal user (read more about Capabilities):

# setcap cap_net_raw,cap_net_admin=eip /usr/bin/iwconfig
