Can someone explain how Ubuntu manages wallpapers?

I am confused about how Ubuntu stores user-selected wallpapers.

I have some pictures I use as wallpapers. We'll call them walla and wallb. Both originate from an encrypted drive that is not automatically mounted. walla is the active wallpaper, but is not in ~/Wallpapers, but wallb is.

So I think "Ok, so Ubuntu must have a place where it copied walla", so to experiment I set wallb.png as the wallpaper and then removed it from ~/Wallpapers. This caused the background to disappear. This left me confused as to where it stored walla, because that encrypted drive I mentioned was not mounted.

Could someone please tell me where Ubuntu stores the active wallpaper and how it goes about deciding when to copy user-provided wallpapers to various destinations?

did you check in `$HOME/Pictures/Wallpapers` for the copy of walla??

My ~/Pictures dir is a symlink to a dir on the encrypted drive, so my ~/Pictures dir does not exist until the drive is mounted.

Active backgrounds are stored in `~/.local/share/backgrounds`. As for how Gnome goes about deciding things ... only a Gnome developer can answer that

@matigo That sounds like an answer.

@mchid only half of one, which is why it's a comment

Can't reproduce that in 21.10. The copy is saved under .local/share/backgrounds, deleting the original does not remove that background. On next login, the dconf key is updated to point to the file in the .local/share/backgrounds folder instead of the original.

I'll start from scratch on Ubuntu 21.10 and reproduce the issue

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
