And here I thought it was /usr/share/backgrounds/default.jpg or /usr/share/backgrounds/default.png.Iguleder wrote:/usr/share/default.jpg or /usr/share/default.png.
Oh well.
To change wallpaper, you would copy a new background jpg/png file to /usr/share/backgrounds as default.png or default.jpg.
If you like the current backgound image, be sure to copy it elsewhere first to keep it.
