Introduction

Compiz Fusion is a project that aims to add more functionality to Compiz by extending it with more plugins, tools and libraries.

Installation

Basic installation can be done using community as repo (see below).

The second way is using nesl's git packages. See Compiz_Fusion_Git for more information.

Install from Community

Make sure the Community repository is enabled and run this command as root to install everything:

# pacman -S compiz-fusion

Run this if you only want gtk-based packages installed:

# pacman -S compiz-fusion-gtk

or this if you only want kde-based packages installed:

# pacman -S compiz-fusion-kde 

If you want select the packages individually, here is a list:

List of packages by group

Entire compiz-fusion group
ccsm, compiz-core, compiz-fusion-plugins-extra, compiz-fusion-plugins-main, compizconfig-backend-gconf, compizconfig-backend-kconfig, emerald, emerald-themes, fusion-icon
KDE compiz-fusion group
ccsm, compiz-fusion-plugins-extra, compiz-fusion-plugins-main, compizconfig-backend-kconfig, emerald, emerald-themes, fusion-icon
GTK compiz-fusion group
ccsm, compiz-fusion-plugins-extra, compiz-fusion-plugins-main, compizconfig-backend-gconf, emerald, emerald-themes, fusion-icon

You might want to install compiz-manager. It will allow you to have session management working. (From what I have understood.)

(more TODO?)

Check Settings

Backend
Depending on the packages you installed, you can use different backends to manage your compiz settings. While gconf / kconf should be fine for Gnome / KDE, the basic Flat-file Configuration Backed should be your choice if want to try out compiz in different Environments without losing the settings in between or you simply use a different Desktop Environment. You can change the used Backend with ccsm ("Settings=>").
Activate important plugins!
Before you do anything else, you might want to check if the plugins that provide basic window manager behaviour are activated or you will have no possibility to drag, scale or close windows as soon as compiz is activated. Among those plugins are "Window Decoration" under Effects and "Move Window" & "Resize Window" under Window Management. You can use ccsm to do that.

Starting Compiz Fusion

Manual (with "fusion-icon")

Launch the Compiz Fusion tray icon:

$ fusion-icon

Note: If it fails, you may try it with dbus-launch:

$ dbus-launch "fusion-icon"

Right click on the icon in the panel and go to 'select window manager'. Choose "Compiz" if it isn't selected already, and you should be set.

If this fails you can start compiz-fusion by using the following commands

$ fusion-icon
$ emerald --replace
$ compiz-manager

If you want to use compiz window decorations make sure you have the "Window Decoration" plugin marked in the compiz settings.

KDE

Manual (without "fusion-icon")

Launch Compiz with the following command once installation is done :

$ compiz --replace ccp &

Start new settings manager:

$ ccsm &

Select all the plugins you like including “decoration” plugin, Add

$ kde-window-decorator --replace

as command string under ‘decoration’ plugin.


Autostart (with "fusion-icon")

You should add a symbolic link to the fusion-icon executable in your KDE Autostart directory (generally located on ~/.kde/Autostart):

$ ln -s /usr/bin/fusion-icon ~/.kde/Autostart/fusion-icon

Next time you start KDE it will load fusion-icon automatically.

Autostart (without "fusion-icon")

Method 1 - Autostart Link

  • You can ensure that Compiz Fusion will always start at login by appending a desktop entry to the KDE autostart directory. Create the file ~/.kde/Autostart/compiz.desktop with the following contents:
[Desktop Entry]
Encoding=UTF-8
Exec=compiz --replace ccp
StartupNotify=false
Terminal=false
Type=Application
X-KDE-autostart-after=kdesktop
  • If you want to use the optional fusion-icon application, launch fusion-icon. If you log out normally with fusion-icon running, KDE should restore your session and launch fusion-icon the next time you log in if this setting is enabled. If it doesn't appear to be working, ensure you have the following line in ~/.kde/share/config/ksmserverrc:
loginMode=restorePreviousLogout

Method 2 - export KDEWM (avoid KWIN)

Using this method will load Compiz-Fusion as the default window manager instead of KWin from the start. This method is faster then loading Compiz-Fusion in the ~/.kde4/Autostart/ (method 1) because it avoids loading KDE's default WM (KWin) first. This way also stops that annoying black screen flicker you might see using other methods (when kwin switches to Compiz on KDE's desktop loading screens).

As root you must create a short script by doing the following in your terminal. This will allow you to load compiz with the switches because doing it directly via export KDEWM="compiz --replace ccp --sm-disable" doesn't seem to work.

$ echo "compiz --replace ccp --sm-disable &" > /usr/bin/compiz-fusion

If this doesn't work, install the "fusion-icon" package and then use this line instead:

$ echo "fusion-icon &" > /usr/bin/compiz-fusion

Ensure that "/usr/bin/compiz-fusion" has executable (+x) permissions.

$ chmod a+x /usr/bin/compiz-fusion

Edit your ~/.bashrc and add the following so KDE will load compiz (via the script you just created) instead of loading KWin.

$ export KDEWM="compiz-fusion"

Note: If you use /usr/local/bin directory it may not work. In that case you should export the script with the path, i.e. export KDEWM="/usr/local/bin/compiz-fusion".

Note: The elegant way for above mentioned method is to include:

KDEWM="compiz-fusion"

line in the ~/.kde4/env/compiz.sh or /usr/env/compiz.sh (system wide).

Method 3 - Use KDE 4.2 System Settings

Go to System Settings --> Default Applications --> Window Manager --> Use a different window manager

If you need to run compiz with custom options select "Compiz custom" (when you run fusion-icon from a terminal you can see the command line with which compiz was started). Create a file called "compiz-kde-launcher" in your /usr/bin directory. Then make the file executable: "chmod +x /usr/bin/compiz-kde-launcher". Here is an example for compiz-kde-launcher:

 #!/bin/bash
 LIBGL_ALWAYS_INDIRECT=1
 compiz --replace --sm-disable --ignore-desktop-hints ccp --indirect-rendering &
 wait

Make sure you have the plugin "Window Decorations" enabled. Depending on what packages you have have downloaded you can choose between serveral window decorators. The recommended ones for KDE are emerald and kde4-window-decorator. The emerald decorator has the advantage that it fits better to compiz's screen handling. Use "CompizConfig Settings Manager" to change the default decorator: Window Decorator -> Command: emerald --replace or kde4-window-decorator --replace.

If you have no window decorations try to add the following line to your "compiz-kde-launcher"-file:

 sleep 1
 kde4-window-decorator --replace&
 # or if you want to use emerald
 # emerald --replace&



GNOME

Autostart (without "fusion-icon")

Create /usr/share/applications/compiz.desktop containing the following:

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=Compiz
Exec=compiz ccp
NoDisplay=true
# name of loadable control center module
X-GNOME-WMSettingsModule=compiz
# name we put on the WM spec check window
X-GNOME-WMName=Compiz

Set a GConf parameter: "gconftool-2 --set -t string /desktop/gnome/session/required_components/windowmanager compiz"

Note: If that doesn't work try Exec=compiz ccp --indirect-rendering instead of Exec=compiz ccp in the above.

Autostart (without "fusion-icon", Gnome prior to 2.24)

This is a way that works if you use GDM (and I'd assume KDM too).

Make a file called /usr/local/bin/compiz-start-boot with the contents:

#!/bin/bash
export WINDOW_MANAGER="compiz ccp"
exec gnome-session

and make executable (chmod +x). Next create the file /etc/X11/sessions/Compiz.desktop containing the following:

[Desktop Entry]
Version=1.0
Encoding=UTF-8
Name=Compiz on GNOME
Exec=/usr/local/bin/compiz-start-boot
Icon=
Type=Application

Select Compiz on Gnome as your session and you're good to go.

Autostart (with "fusion-icon")

To start Compiz fusion automatically when starting a session add

"Compiz Fusion" (Name:)

and

"fusion-icon" (Command:)

to the applications that start with your session. You can do this by going to:

[System] -> [Preferences] -> [Sessions] -> [Startup Programs]

Adding "Compiz Fusion" to the list might be a good idea too so you can switch back to Metacity if need be.

Also set the following parameter, otherwise fusion-icon might not load windows decorator.

gconftool-2 --type bool --set /apps/metacity/general/compositing_manager false

Xfce

Xfce autostart (without "fusion-icon")

Starting Compiz with the XFCE session manager. This will start Compiz directly without loading Xfwm.

Please note the change to xml config files in XFCE newer than 4.2


To install the session manager, run this command as root:

# pacman -S xfce4-session


Now we have to configure the default/failsafe session of XFCE.


Edit the following file

# nano ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml

Or to make the change for all XFCE users (root access required)

# nano /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml


Replace the xfwm startup command,

 <property name="Client0_Command" type="array">
   <value type="string" value="xfwm4"/>
 </property>

with the following:

 <property name="Client0_Command" type="array">
   <value type="string" value="compiz"/>
   <value type="string" value="ccp"/>
 </property>


To prevent the default session from being overwritten you may also add this:

 <property name="general" type="empty">
   ...
   ...
   <property name="SaveOnExit" type="bool" value="false"/>
 </property>


To remove the existing sessions, run:

rm -r ~/.cache/sessions


Xfce autostart (with "fusion-icon")

Method 1:

This will load Xfwm first then replace it with Compiz.

Open the XFCE Settings Manager & then Sessions & Startup. Click the Application Autostart tab.

Add

  (Name:) Compiz Fusion
  (Command:) fusion-icon

Method 2:

Edit the following file (settings in this file is used in preference)

nano ~/.conf/xfce4-session/xfce4-session.rc

Or to make the change for all XFCE users (root access required)

# nano /etc/xdg/xfce4-session/xfce4-session.rc

Add the following

[Failsafe Session]
Client0_Command=fusion-icon

Comment out Client0_Command=xfwm4 if it exists.

This will cause xfce to load Compiz instead of Xfwm when the user has no existing sessions.

To prevent the default session from being overwritten you may also add

[General]
AutoSave=false
SaveOnExit=false

To remove the existing sessions

rm -r ~/.cache/sessions

As a standalone WM

Write a simple script called, say, start-fusion.sh:

#!/bin/sh
# add more apps here if necessary or start another panel, tray like pypanel, bmpanel, stalonetray
xfce4-panel&
fusion-icon

Make it executable and add it to ~/.xinitrc, like this:

exec start-fusion.sh

Feel free to use a different panel, tray, or start a whole bunch on applications with your session. See forum thread for more info.

Add a root menu

To add a root menu similar to that in Openbox, Fluxbox, Blackbox etc. you must install the package compiz-deskmenu from the AUR. Upon a restart of Compiz-Fusion, you should be able to middle click on your desktop to launch the menu.

If it does not automatically work, enter the CompizConfig Settings Manager, and in Commands tab, within the General Settings menu, ensure that there is a command to launch Compiz-Deskmenu, and the appropriate key binding is set to Control+Space.

If it still does not work, enter the Viewport Switcher menu, and change "Plugin for initiate action" to core (NOTE: for versions 0.8.2+ it's 'commands' instead of 'core'), and "Action name for initiate" to run_command0_key.

Troubleshooting

Make sure that the environmental variable $XLIB_SKIP_ARGB_VISUALS is not set


KDE 4.2 :

-Panel/taskbar is visible when running apps in fullscreen mode:

Enable Window Rules plugin and add under ABOVE : state=fullscreen
