I've see the slide show (Pictures folder) screensaver. I've also seen how to change the background behind my login screen. What I haven't been able to figure out is how to display a slide show as a screensaver over my login screen. Can someone please point me in the right direction?

If you're using GDM, I would reccomend switching to another DM that's easier to customize.– TheInitializerCommented Oct 25, 2016 at 23:19

I don't think this is possible looking at how GNOME3 and GDM currently work. At least not without having to restart /etc/init.d/gdm3 every time you want the image to rotate. This seems impractical.
The steps to change the login and the lock screen wallpaper are discussed here in this post titled: Change desktop, login and lock screen wallpapers in GNOME 3.4.
For example
I'll highlight the steps to change GDM's wallpaper just so you get a general idea of what I'm talking about.
step 1 - become the gdm user
su - gdm -s /bin/bash
step 2 - change the image
`dbus-launch | sed 's/^/export /'`
gsettings set org.gnome.desktop.background picture-uri file:///home/fabhax/wallpapers/NATURE-SkyStone_1920x1200.jpg
step 3 - restart gdm3
/etc/init.d/gdm3 restart
The steps are similar to do the same thing for the screen lock wallpaper. This could be scripted but it seems hackish.
Leave a comment if this is something you'd seriously like to have.

Thanks for the reply, link, and code example. We already change our login wallpaper. I really want to cover the login screen with a screensaver that will go away when the mouse or keyboard is touched like a normal screensaver. I was hoping at logout there was a way to trigger the built in screen saver to go on. Commented May 17, 2013 at 19:59
