FvwmBacker can only be invoked by fvwm. Command line invocation of the FvwmBacker module will not work.
The FvwmBacker module provides functionality to change the background when changing desktops. Any command can be executed to change the backgrounds. Actually, any arbitrary command can be sent to fvwm to execute, so you could also do things such as changing window border colors, etc.

initialization by inserting the line

in the .fvwm2rc file.
FvwmBacker can be started using a ’Module FvwmBacker’ command or stopped using a ’KillModule FvwmBacker’ command at any time when fvwm is running.
FvwmBacker must reside in a directory that is listed in the ModulePath option of fvwm for it to be executed by fvwm.
If either the Desk or the Page parts are omitted, the command is not executed if only the desk or the page is switched. If neither is given, the command is executed only once when the module is started. This is not the same as using asterisks for the numeric arguments: if asterisks are used, the command is always executed when only the desk or page changes, if the corresponding part is omitted, the command is never executed when only the desk or page changes.
If the command is -solid FvwmBacker uses the next argument as a color in the X database and sets the background to that color without generating a system call to xsetroot (only single word color names may be used).
If the command is colorset FvwmBacker uses the background specified in colorset n for the given desk. Please refer to the man page of the FvwmTheme module for details about colorsets.
Otherwise the command is sent to fvwm to execute.

It is functionally equivalent to omitting the page coordinates with *FvwmBacker: Command:
