Window Managers Explained - page 4
Changing your Window Manager
Once your X-Server starts, it runs the commands in the XClients script to start the window manager. Other programs that should run on startup can also be placed in the Xclients script.
To change your window manager you can edit the Xclients
script. The system-wide version of the Xclients
script is /usr/X11R6/lib/X11/xinit/Xclients.
Unless you want your changes to affect the default settings for all users on your system, it is a good idea to leave this file alone. The file $HOME/.Xclients
is your home directory) can contain a user-specific version of the Xclients
file. Each user on the system is able to choose a personal window manager by customizing the
file. This file is a shell script, and can be changed with any text editor. Using the system default version as a starting point is a good idea. Often you can change the default window manager by editing one line in the file, and some Linux
distributions will allow you to change your window manager through a GUI interface. Each
window manager has its own configuration file, or configuration directory tree. See the
documentation for your window manager to learn more about customizing your environment.
