Changing the GNOME 3.10 lock screen art

I upgraded to the Fedora 20 work-in-progress tree on my laptop recently, and one of the first things I noticed about GNOME 3.10 was the new lock screen. Specifically, this:



My wife walked by, saw it, and asked me "what is that ugly thing on your computer?" I was forced to simply shrug in agreement.

Now, I admit, I do not possess the finest of tastes. My tastes are less caviar and champagne and more bacon and beer, but that's fine for me. I know what I like, and I know that this pink spray is not it. I figured there might be others who don't appreciate the choice of artwork here either, so I took a few moments and figured out how to change it.

If you go into the gnome-control-center (accessible from the top right menu, then clicking the "tools" bubble), then click on "Background", it will open a window where you can change Background and Lock Screen. Clicking on Lock Screen brings up an interface where you can choose from a set of art (either Wallpapers, Pictures, or Colors) that has been hardcoded by the GNOME upstream for your viewing pleasure. Pick one of these pictures and the Pink Panther nightmare is gone.

... but what if you want a custom picture there? I like to customize my desktop. I changed my background to one of the optional F19 backgrounds (the one with the tree frog), and I've been using a custom plymouth plugin for the bootsplash with an animated Hypnotoad for a while now. I found a clever picture of the Futurama splash screen on the internets:



Okay, so maybe that's only funny to me, but I kept thinking that the Pink Volcano reminded me of that. Download a copy of that file (or whatever JPG or PNG you like), and put it into ~/Pictures. Now, it will show up in the gnome-control-center tool when you restart it. Then you can select your custom lock screen.

I can't help but wonder why they do not have a file selector here. Seems like the sort of thing that would be nice. Maybe it is coming soon.

EDIT: Documented using ~/Pictures instead of altering the hardcoded wallpaper XML list.

Or you could just drop the file in ~/Pictures...
Lock screen customization is one of the new 3.10 features. I agree, this pink "volcano" does not really fit with the default background color. Since it's new and has been asked by many. Now, we feel the need to customize this feature.. Hey, isn't that smart? We are all going to see how to do it. You've already promoted this feature :)

Ok, it goes against the GNOME way... but I like thinking about forcing people to ask question in order to understand how their system work.

Under the Fedora Project, we can also probably define a Fedora default one, as we do with the wallpaper. It's probably on the Design team hand.
there was a discussion about this on fedora-desktop list last month
Well as Bastien already pointed out in the post above yours, the premise for this post was wrong. Any photo in your ~/Pictures directory will show up in the Pictures tab, so there is no 'hardcoding'. And beyond that adding something to the panel for selection a new image is planned and also in GNOME 3.10.1 you can drag and drop an image onto the control panel.

The premise wasn't wrong, the way I solved it may not have been the ideal mechanism, but how was I to know that ~/Pictures was a magical place? :)

Neat!
