I have Ubuntu 16.04.1 and when I right click a photo and select "Set As Wallpaper" the function does not work. But I am able to get it working by going into System Settings and using the + button in Personalization to set a new wallpaper. It's very annoying though, is there any way to fix this problem?
- I tested on another account and the problem went away
- there are no other DEs installed. GNOME was previously installed but it is now uninstalled.
it doesn't work on Thunar either. Forgot to say that I had recently switched to Thunar for my file manager (but my desktop is still Unity)
