FvwmBacker(0.1)                                                FvwmBacker(0.1)

       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.

       warranties of any kind about the use of this module.  Use this modules
       at your own risk.  You may freely use this module or any portion of it
       for any purpose as long as the copyright is kept intact.

       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 following is the only supported option at present:

       *FvwmBackerDesk DeskNumber command
              Specifies the command to execute when the specified DeskNumber
              becomes active.

              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
       initialization commands:

       # 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
