For Ubuntu 12.04 :

Here's how you can change the default wallpaper. For example, we'll set it to the included Wild Wheat (/usr/share/backgrounds/WildWheat_by_Brian_Burt.jpg):

  • Within the LiveCD chroot, open the following file with nano as,

    nano /usr/share/glib-2.0/schemas/10_gsettings-desktop-schemas.gschema.override
  • Change the below line to the path for your file:

  • For our example, that becomes:

  • Finally, compile the modified schemas with:

    glib-compile-schemas /usr/share/glib-2.0/schemas

For Ubuntu 14.04 :

Say you want to make /usr/share/backgrounds/Reflections_by_Trenton_Fox.jpg as your default wallpaper.

  • Within the LiveCD chroot, open the following file with nano as,

    nano /usr/share/gnome-background-properties/ubuntu-wallpapers.xml
  • Change the following line:

  • To (in our case):

  • Also edit the <stringvalue> in the following file,

    nano /var/lib/gconf/debian.defaults/%gconf-tree.xml
  • Change the line,

  • To (in our case):

This seems like it should work, but for some reason it isn't. I suspect remastersys is doing something funny. – jlewis42 Sep 11 '12 at 19:27
Yes, Remastersys is often problematic because of how it works compared to UCK or Ubuntu Builder. Perhaps try one of those? – izx Sep 11 '12 at 21:09
With Ubuntu 13.10, it is /usr/share/glib-2.0/10_ubuntu-settings.gschema.override :) – Benoît Legat Mar 31 '14 at 14:01
