I've been trying out various desktops since I installed Ubuntu 12.04; so far I'm really liking Xfce. It's logical and highly customizable. I was also delighted to find that it hadn't abandoned the screensaver. My question is, is there a way to have it do a slideshow from my picture folder? I do a lot of photography and loved this feature with the old Gnome desktop in Ubuntu 10.04. Screensaver Preferences gives me a random mode, but it's all pre-installed stuff.
