Common Issues

1. Wallpaper not changing : If your wallpaper is not changing, then open an issue and show me the output of echo $DESKTOP_SESSION.

2. Not working on XFCE : If this script is not working on xfce, then open the terminal and run xfconf-query -c xfce4-desktop -m and change the wallpaper (any) via xfce4-settings-manager.
   In the terminal, xfconf-query will print lines starting with set:, which show which properties have been changed, check screen & monitor values and modify the script accordingly.

110   ## For XFCE
111   if [[ "$OSTYPE" == "linux"* ]]; then
112      SCREEN="0"
113      MONITOR="1"
114   fi

3. Autostart : If you want to autostart the script with desktop, you can add it to your WM autostart file & if it doesn't work for you, you can create a desktop file in $HOME/.config/autostart dir.

$ cd $HOME/.config/autostart && touch bwall.desktop

# Add this to bwall.desktop file

[Desktop Entry]
Name=Battery Wallpaper
Comment=Set desktop background according to battery percentage, with charging animation.
Exec=/usr/bin/bwall -s leaves &
Type=Application

Categories=Accessories;

Quick FYI

• In KDE, bwall changes the wallpaper in all the Activities.
• You can add bwall -s style & to your wm autostart file to set it as wallpaper after login.
• Have Fun!
