I'm running Xubuntu 14.04 64-bit. I installed Wally but couldn't get it to work so I uninstalled it. When I right-clicked on the desktop, chose Desktop Settings, the folder for the wallpapers was still set to the .wally folder. I deleted that folder and now when I try to go back to the original folder that contains all the wallpapers, it won't save the settings. How can I fix this?
