Select a window manager at X startup wmanager is a small X11 application for selecting a window manager at X startup. wmanager looks for a file named '.wmmanagerrc' in the user's home directory which contains a list of window managers; you can create such a file with wmanagerrc-update. You can also use wmanager-loop that runs window managers chosen by the user until told to exit. From Debian 3.0r0 APT
