Since Jessie became stable, there is a flat gray background on the XFCE4 desktop and I cannot change it. My normal configuration is that XFCE4 should use a list of pictures and change the background regularly (something that I don't think the other systems can do). This is not working anymore.
Even Wallpapoz (my second choice) which in the past could work with XFCE4 would not do it's job. Now I am using cinnamon + wallpapoz. I would prefer however to use XFCE4. Regards Johann -- Because experiencing your loyal love is better than life itself, my lips will praise you. (Psalm 63:3)
