See your mail: > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=858643#29 I had missed it was for post stretch upgrade last time I looked into this, so I hadn’t come to any conclusion. I initially thought we could "just" patch debian-edu-artwork to ship an SVG versions of the edu-spacefun wallpaper, but there’s no such thing in the source repository even going back in time to squeeze. There are SVGs for edu-spacefun but they look like imports from bitmap with vain attempts to make them vector… By itself it’s a problem since it means these wallpapers are essentially sourceless and we cannot easily adapt them should the need arise (higher resolution, etc). Anyway we should never break on upgrade for even if the active theme pack is incomplete, I’m thus reassigning the bug to desktop-base and will conditionally create the alternatives for the active theme only if the target exists in that theme. Also I can see the rationale of theme packs providing a bitmap background instead of SVG, if it’s based on a photo for instance. Currently desktop-base doesn’t provide an easy way to support that. What I can think of is for each theme pack to provide a "default-wallpaper" symlink to their wallpaper file of choice and the desktop-background alternative will target link for the active theme, so it works whatever wallpaper/resolution/format the theme wants as default. For buster I’ll create the links for the themes included in desktop-base and the *all* debian-edu-artwork-* themes should do the same. That would be for example with softwaves: softwaves-theme/wallpaper/contents/images$ ls -l 1920x1080.svg default-wallpaper -> 1920x1080.svg … and second example with debian-edu-spacefun: debian-edu-spacefun-theme/wallpaper/contents/images$ ls -l 1920x1080.png default-wallpaper -> 1920x1080.png … Would that be OK with you ? On a side note I don’t like very much the concept of a single wallpaper image that the "desktop-background" alternative provides. It cannot support various screen sizes and ratios correctly. Gnome or KDE Plasma get it right by selecting one among n possible resolutions to match the screen size at runtime, but getting this done for all Desktop Environments seems far-fetched. If anyone from other DEs is listening and want to use either /usr/share/gnome-background-properties/*.xml or KDE Plasma’s /usr/share/wallpaper structure, don’t refrain. :) Cheers, --Aurélien
