What is Compiz?
According to Compiz.org, Compiz is: "... an OpenGL compositing manager that use GLX_EXT_texture_from_pixmap for binding redirected top-level windows to texture objects. It has a flexible plug-in system and it is designed to run well on most graphics hardware. Okay, this description isn’t really meaningful. In a nutshell, Compiz is a compositing manager, which means that it enhances the overall user interaction by adding fancy effects to your windows, from drop shadows to awesome desktop effects like the Desktop Cube or the Expo view. Compiz can also be a window manager, which means that it is the software between you and your desktop apps. It enables you to move or resize windows, to switch workspaces, to switch windows easily (using alt-tab or so), and so on."
To install Compiz, you must first emerge it:
# emerge compiz compiz-fusion emerald hicolor-icon-theme
As a standalone window manager
For Compiz to run as a standalone window manager, you must first change your ~.xinitrc file:
exec compiz ccp & emerald --replace & fusion-icon & gnome-terminal & conky
The lines after the first two can be any applications that you would like to launch when the X.org server starts.
Now, with compiz installed and ready to run, try starting it:
If it starts successfully, you will be greeted with a black screen and whatever programs you added to your ~/.xinitrc after line two. At this point, you may be wondering "Why are there no decorations around my windows?" There are no decorations because Compiz comes configured to not decorate windows. In your terminal that was launched from the ~/.xinitrc file, type in:
Below is a table which contains information on the avialable compiz plugins.
