Common Issues
-
Wallpaper not changing : If your wallpaper is not changing, then open an issue and show me the output of
echo $DESKTOP_SESSION. -
Not working on XFCE : If this script is not working on xfce, then open the terminal and run
xfconf-query -c xfce4-desktop -mand change the wallpaper (any) via xfce4-settings-manager.
In terminal, xfconf-query will print lines starting withset:, which show which properties have been changed, checkscreen&monitorvalues and modify the script accordingly.
105 ## For XFCE
106 if [[ "$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!
