I have the same behavior on my installation. However when I started messing with the last image settings rather than setting image path, the wallpapers changed for me.. Perhaps this could be an issue with what the name of the setting itself is not stating explicitly that it is where the update needs to occur?
( I do not know if setting the workspace mode to false had any affect, as I did it before my testing ) Here is what I used to get the wallpaper to finally change: xfconf-query -c xfce4-desktop -p /backdrop/single-workspace-mode -s false xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorDP-3/workspace1/last-image -s /home/chubbard/Pictures/SFW_Humor/we_have_your_server_give_us_cash.jpg xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorDP-3/workspace0/last-image -s /home/chubbard/Pictures/SFW_Humor/wrong_way.jpg Output: xfconf-query -c xfce4-desktop -p /backdrop -lv /backdrop/screen0/monitor0/brightness 63 /backdrop/screen0/monitor0/image-path /home/chubbard/Pictures/SFW_Humor/bondage.jpg /backdrop/screen0/monitor0/image-style 0 /backdrop/screen0/monitor0/saturation 0.000000 /backdrop/screen0/monitorDP-3/workspace0/backdrop-cycle-enable false /backdrop/screen0/monitorDP-3/workspace0/backdrop-cycle-random-order true /backdrop/screen0/monitorDP-3/workspace0/backdrop-cycle-timer 1 /backdrop/screen0/monitorDP-3/workspace0/color-style 0 /backdrop/screen0/monitorDP-3/workspace0/image-style 4 /backdrop/screen0/monitorDP-3/workspace0/last-image /home/chubbard/Pictures/SFW_Humor/wrong_way.jpg /backdrop/screen0/monitorDP-3/workspace1/color-style 0 /backdrop/screen0/monitorDP-3/workspace1/image-style 3 /backdrop/screen0/monitorDP-3/workspace1/last-image /home/chubbard/Pictures/SFW_Humor/we_have_your_server_give_us_cash.jpg -- SNIP -- /backdrop/single-workspace-mode false /backdrop/single-workspace-number 1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1314829 Title: "Set as Wallpaper" doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ristretto/+bug/1314829/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
