A few days ago I realized Ubuntu One was no longer syncing. I found a few relevant threads on the Forum to research later. Today I needed to log in to Ubuntu for a brief moment and was surprised that a notification popped up telling me 4 new files were being synced in Ubuntu One. This was automatic simply by virtue of having logged in to the Unity desktop. That puzzled me. Most of the time I log in to a Xubuntu session, where I initially had no problems with U1. Is there any reason it should stop syncing in Xubuntu (Xfce 4.10) but automatically sync in Ubuntu?
