I have recently dual-booted my Windows 7 with Ubuntu 14.10 , and I am really enjoying it. I want to use all the Ubuntu wallpapers for Windows also, how can I get them? (Where are the Ubuntu wallpapers stored? As in , which directory, so that I can just copy them and get it on Windows 7 also.)
You can actually see where the current background is stored, by running (in a terminal window) the command:
gsettings get org.gnome.desktop.background picture-uri
I get for example:
That means my wallpaper is stored in
/usr/share/backgrounds. In 14.10, that is the default location for wallpapers.
Default Ubuntu wallpapers are stored in /usr/share/backgrounds/. For each Ubuntu release, there is a new package created for the wallpapers of that release. For 14.10, the package name is ubuntu-wallpapers-utopic, you can get to see the list of wallpapers by issuing the command
dpkg -L ubuntu-wallpapers-utopic | grep .jpg$
You can also find the wallpapers for the 14.10 release in http://packages.ubuntu.com/utopic/all/ubuntu-wallpapers-utopic/filelist (files that end with .jpg).
