Fedora 16 Alpha is coming out soon and they have selected Fedora 16 wallpaper. Here is how I installed it in Fedora 15:

wget http://kojipkgs.fedoraproject.org/packages/verne-backgrounds/15.91.0/1.fc16/noarch/verne-backgrounds-15.91.0-1.fc16.noarch.rpm
rpm -i verne-backgrounds-single-15.91.0-1.fc16.noarch.rpm
rpm -i verne-backgrounds-15.91.0-1.fc16.noarch.rpm

Then, select the new wallpaper in background settings.

[HOWTO] Change GDM 3 Theme and Wallpaper

I am using Debian Squeeze Testing and I have gdm3 installed.  I wanted to change the default gdm theme and here is how I did it.

I opened the file /usr/share/gdm/greeter-config/20_debian in a text editor as root and changed the line containing “/desktop/gnome/background/picture_filename” and gave the full path to the new location of wallpaper. I also changed the line containing “/desktop/gnome/interface/gtk_theme” and wrote the name of theme instead of the default (in my case it was Clearlooks and I changed it to an installed theme Equinox). Then I saved the file and logged out to see the changes.

While changing the theme, make sure that the theme is installed as available to all users (i.e. in /usr/share/themes).
