One of the things I can do on XFCE-desktop that I could not find an easy
way to do on the other desktop environments (I have tried Gnome, Cinnamon,
Mate and maybe KDE), is to have a different background image for every
monitor and that I can change image at a specified time. So I have a
diectory with many images which randomly become my background image every
two minutes as my settings is at the moment.
Because experiencing your loyal love is better than life itself,
my lips will praise you. (Psalm 63:3)
