First and foremost, I would like to thank the System 76/Pop!_OS team for their great distro and user experience, and to state that I’m eagerly awaiting the release of this awesome new DE. That said, I would like to leave here a suggestion that I believe would make the new DE even more awesome.

It would be cool If cosmic-bg supported wallpapers from Wallpaper Engine and the like, there already are some projects that bring wallpaper engine support into Linux, namely Wallpaper Engine for Kde KDE plugin and linux-wallpaperengine.

I do understand that if this feature is ever adopted It would probably be long after the release of Cosmic.

The cosmic-bg package doesn't install a configuration file, and it prints Config file error, falling back to defaults: Failed to get find config file (it probably shouldn't show an "error" if it's expected to not have a config on default installs).

It looks like the default uses CosmicBgImgSource::Wallpapers, but $HOME/Pictures/Wallpapers doesn't exist or have wallpapers by default.

I guess this is configuration is really a placeholder until we establish how wallpaper configuration should work, but in any case it should something from /usr/share/backgrounds/pop.

This is a missing feature in Linux as a whole, and I was only able to find one app that does it and it barely works. This should be an option in the settings when setting up a wallpaper that has the resolution to span across two monitors (given one has two monitors).

Laptop connected to an external display. Disable either, and the cosmic wallpaper disappears. Log out/in restores the wallpaper.

As title stated.

Hello.
I think that's the correct place for that feature request, but if not then I am sorry. I'm just getting familiar with pop_os before next release comes out.

Wallpaper Engine allows users to set videos and webpages as their desktop wallpaper, but it unfortunately only works on Windows (with plans to support Steam Deck's KDE Plasma). It would be nice to have a support in pop_os for setting a webpage file as wallpaper since it allows for easy customization of some animations that can make the desktop look prettier.

I've only seen this feature on macOS and nowhere else.

The Issue

When setting the user's wallpaper to a directory of images, the only option Pop!_OS 22.04 (and every other Ubuntu-derivative) has for cycling the next wallpaper is via a timer. After the timer is up, the wallpaper is changed. But what if I want to set other triggers for a wallpaper to change?

Request

I'd really like an option in the Wallpapers settings to cycle to a new wallpaper on Login/Startup, so when I turn my computer on, I'm greeted with the "wallpaper of the day," so to speak. Additional settings could be added in, such as On Wake from Suspend. In these cases, the user wouldn't see the change happen, the wallpaper would be chosen and loaded before the desktop environment is displayed.

After each restart the first photo (alphabetically) is set as the wallpaper. This means if you have a large repository of wallpapers, you'd never see the last photos but see the first ones every time.

I suggest the name of the last shown picture be saved and used to resume after each restart.

First and foremost, I would like to thank the System 76/Pop!_OS team for their great distro and user experience, and to state that I’m eagerly awaiting the release of this awesome new DE.

That said, I would like to leave here a suggestion that I believe would make the new DE even more awesome. It would be cool If we could select a videos as wallpapers (one for each screen), so we could have Live wallpapers in the vain of projects like the ones linked below.

I do understand that if this feature is ever adopted It would probably be long after the release of Cosmic.

Hidamari: https://github.com/jeffshee/hidamari
Flatpak package that gives the ability of setting a video as wallppaper

Hanabi: https://github.com/jeffshee/gnome-ext-hanabi
Gnome extension that provides the same functionality of Hidamari, but with better Gnome support.
