SYNOPSIS

wrenctl install wallpapers                     choose basic and/or strong; pictures go in ~/Pictures/Wallpapers
wrenctl remove wallpapers                      take out what it put there (your own pictures stay)
wrenctl manual wallpapers                      print the manual steps below

Super+] / Super+[                              step through them as your wallpaper
wallpaper pick                                 choose one by name

Pictures to choose your wallpaper from (the base's ~/Pictures/wren/desktop, parts/wallpaper.sh), copied into ~/Pictures/Wallpapers from data/wallpapers/. They come with Wren Linux, so nothing is downloaded and Wren Linux's signature covers them. CREDITS.txt names each one's author, page, licence and what was changed.

• basic, ticked at first: wrens, art, Earth and space.
• strong, never on unless you tick it: real violence and death, and nudity. Without a terminal to ask on, it isn't copied. Unticking it later takes those pictures out again.

An earlier version fetched pictures from NASA, ESA and Debian. NASA's and ESA's (nasa_, webb_, earth_) stay yours: neither an update nor wrenctl remove wallpapers touches them, and a picture you already have isn't replaced by a smaller one.

Pictures of your own (an image search, saved through Firefox into ~/Downloads) can go in the same folder: Wren Linux never changes or removes them.

Pexels has more for your own screen: https://www.pexels.com/search/desktop%20wallpaper/. They're free to use there with no credit needed, but its terms don't allow passing them on as they are, so Wren Linux doesn't ship any. Its licence, which can change: https://www.pexels.com/license/. Wren Linux only names the site: nothing here opens or fetches it.

Super+] and Super+[ step through the folder as your wallpaper, and wallpaper pick lists it by name (parts/wallpaper.sh). README.txt there says the same.

wrenctl remove wallpapers brings back the default wren if one of its pictures is your wallpaper, or if you chose "No wallpaper". A picture of your own that you chose stays up.

LIMITS

• Most need a credit if you share them on, and some must be shared under the same licence: CREDITS.txt says which.
• Commons lists some pictures as public domain, and Wren Linux hasn't confirmed that further.
• Pictures from an image search are usually someone's copyright: fine on your own screen, not to share on.

MANUAL INSTALL

mkdir -p ~/Pictures/Wallpapers
cp -n @WREN_DIR@/data/wallpapers/*.jpg @WREN_DIR@/data/wallpapers/*.png \
    @WREN_DIR@/data/wallpapers/CREDITS.txt ~/Pictures/Wallpapers/
# Only if you want the strong ones: real violence and death, and nudity
# cp -n @WREN_DIR@/data/wallpapers/shock/*.jpg ~/Pictures/Wallpapers/

To undo: delete the pictures you copied, from ~/Pictures/Wallpapers. If one of them is your wallpaper, or you chose "No wallpaper", this brings back the default wren (with your own pictures in the desktop folder, the newest of those instead):

rm -f ~/Pictures/wren/desktop/chosen.jpg ~/Pictures/wren/desktop/chosen.png ~/.cache/wren/chosen-wallpaper
swaymsg reload
