Comment 2 for bug 1041408

Hi,

just tried to get this working and was lucky.
On Ubuntu 12.04 you can run CreBS by downloading the latest version on the CreBS homepage.
Decompress it and run sudo install.sh out of the uncompressed directory.
After that you should find a file named crebs in /usr/local/bin
Run it and create your slideshow.

Unfortunaly that didn't helped me out. The system put out a message that my slideshow was set but it wasn't.
Crebs created an xml file in /home/.crebs
I moved this file to /usr/share/backgrounds/contest.
Then you have to switch to /usr/share/gnome-background-properties
There you find existing xml files which rever to the folder /backgrounds/contest.
You have to create an xml file with the structure of the existing ones:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE wallpapers SYSTEM "gnome-wp-list.dtd">
<wallpapers>
  <wallpaper deleted="false">
    <name>Name of slideshow</name>
    <filename>/usr/share/backgrounds/contest/anyname.xml</filename>
    <options>zoom</options>
  </wallpaper>
<! -- REPEAT THIS SECTION FOR EVERY PICTURE -->
  <wallpaper>
    <name>picname</name>
    <filename>pathtofile/picname.jpg</filename>
    <options>zoom</options>
    <pcolor>#000000</pcolor>
    <scolor>#000000</scolor>
    <shade_type>solid</shade_type>
  </wallpaper>
<! -- REPEAT THIS SECTION FOR EVERY PICTURE -->
</wallpapers>

If you're good at scripting this will be easy.

Now you should be able to choose your slideshow in 'change background'.

Hope it could help.
