FvwmBacker - the FVWM background changer module
FvwmBacker is spawned by fvwm, so no command line invocation will work.
The FvwmBacker module provides functionality to change the background
when changing desktops. Any command can be executed to change the
backgrounds. The commands used to change the backgrounds must exit
after changing the root window, (i.e. ’xv -root zzz.gif’ does not,
without the -quit option) otherwise FvwmBacker will hang.
The FvwmBacker module is the original work of Mike Finger.

During initialization, FvwmBacker will scan the same configuration file
that FVWM used during startup to find the options that pertain to it.
These options are discussed in a later section.
FvwmBacker can be invoked by fvwm during initialization by inserting
the line ’Module FvwmBacker’ in the .fvwmrc file.
FvwmBacker must reside in a directory that is listed in the ModulePath
option of FVWM for it to be executed by FVWM.
The follow option is the only only support at present
*FvwmWinListDesk DeskNumber command
Specifies the command to execute when the specified DeskNumber
If the command begins with -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.
The following are excepts from a .fvwmrc file which describe FvwmBacker
# Set Up Backgrounds for different desktops.
*FvwmBackerDesk 0 -solid steelblue
*FvwmBackerDesk 1 -solid midnightblue
*FvwmBackerDesk 2 -solid yellow
*FvwmBackerDesk 3 xpmroot /usr/include/X11/pixmaps/background2.xpm
