I am running Ubuntu 10.04. I installed Xubuntu but I'm using the Gnome desktop. Recently my desktop started changing, downloading random pictures from somewhere. I don't remember installing an application to do this, but I must have. Unfortunately I don't remember what its name is.
Does this behavior ring any bells? Alternatively, what can I do to identify which application is doing this? (There isn't anything unusual in my Startup Applications.)
