Usage

Though you can pick colors, Here's a list of all supported color names.

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 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.

105   ## For XFCE
106   if [[ "$OSTYPE" == "linux"* ]]; then
107       SCREEN="0"
108       MONITOR="1"
109   fi

FYI

• In KDE, it changes the wallpaper in all the Activities.
• If you can improve it, you're welcome.
• Have Fun!
