🦋 FvwmBacker(1) 🦋

okay bestie, meet FvwmBacker 💅 It's the FVWM background changer module, and it lives in the General Commands Manual 📖 Let's get into it 🌸

✨ NAME ✨

FvwmBacker - the FVWM background changer module 🎀

💖 SYNOPSIS 💖

Okay so FvwmBacker is spawned by fvwm, so no command line invocation will work 🙈 Don't even try typing it into your terminal, it's giving nothing 💀

🌈 DESCRIPTION 🌈

The FvwmBacker module changes your background whenever you switch desktops 🖼️ Any command can be executed to change the backgrounds, literally any command, no cap ✨

⚠️ Heads up, bestie: the commands you use to change the backgrounds must exit after they change the root window. For example, xv -root zzz.gif does not exit on its own without the -quit option, and if that happens, FvwmBacker will hang 💀

👑 COPYRIGHTS 👑

The FvwmBacker module is the original work of Mike Finger 💜

🧚 INITIALIZATION 🧚

During initialization, FvwmBacker scans the same configuration file that FVWM used during startup to find the options that pertain to it 🔍 These options get their own spotlight in a later section (see CONFIGURATION OPTIONS).

🍓 INVOCATION 🍓

FvwmBacker can be invoked by fvwm during initialization by adding the line Module FvwmBacker to your .fvwmrc file 🌸

FvwmBacker has to live in a directory that's listed in the ModulePath option of FVWM, otherwise FVWM won't run it 🥺

💜 CONFIGURATION OPTIONS 💜

The following option is the only one supported at present, so it's giving main character energy 👑

• *FvwmWinListDesk DeskNumber command
  • Tells FvwmBacker which command to run when the chosen DeskNumber becomes active 🦋
  • If the command starts with -solid, FvwmBacker takes the next argument as a color from the X database and sets the background to that color, without making a system call to xsetroot ✨ Only single-word color names work, so no fancy multi-word names, bestie 🙅

🎀 SAMPLE CONFIGURATION 🎀

Here are some excerpts from a .fvwmrc file that show FvwmBacker's 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

Okay bestie, that's the whole tea ☕ This page came from the 3rd Berkeley Distribution, dated September 8th, 1994, and it's still iconic FvwmBacker(1) energy 🦋✨💖
