I just set my default file manager back to Nautilus and confirmed that this is indeed the cause. I wish there was an edit button so I didn't have to triple post.

Even when using the Variety wallpaper changer app, it will work fine and then suddenly the wallpaper will revert to the back to the default Unity wallpaper. The workspace switcher will show what's supposed to be the wallpaper. If you lock your session the screen it displays the correct wallpaper. Rebooting seems to show the correct wallpaper but then it will turn into - the default Unity wallpaper again + the default Unity wallpaper again. + + ** The problem seems to be caused by Cinnamon launching Nautilus. You + can test this with "xdg-open $HOME" in terminal. I used the command + "xdg-mime default nemo.desktop inode/directory application/x-gnome- + saved-search" to switch the default file manager to Nemo and it seems to + have stopped the problem from occurring. ~SuperMechaCow -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581263 Title: Problems with wallpapers in Cinnamon 3.0 with Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cinnamon/+bug/1581263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
