It seems like "xfce4-desktop.xml" would be it... have you tried editing the path in that config file to reflect the path of your desired background and restarting, then logging in and out? The line that says "value=" that is

                 Hi All,

                 I posted this to the regular Xfce group, but no joy.

                 I just installed a new workstation with
                 Fedora-Live-Xfce-x86_64-23-10.iso.  It comes with Xfce 4.12

                 Problem with Desktop Settings:  It is suppose to look like:
            http://jsmylinux.no-ip.org/wp-content/uploads/2013/12/WorkSpace-Wallpaper-01.png

                 But what I get is a blank "wallpaper for ...".  When I
                 go to select the folder, after exiting and restarting
                 settings, it goes back to "none".  The wallpaper
                 area always stays empty.

                 I also installed Fedora-Live-Xfce-x86_64-23-10.iso to
                 a virtual machine and was able to duplicate the issue
                 with the exception that the virtual machine won't move
                 off of "images" and does show three blue wallpapers.

                 $ ps ax | grep -i xfdesktop
                 2429 ? Sl 0:01 xfdesktop --display :0.0 --sm-client-id
                 29b1e4965-d809-48ff-92e2-dc5e898ee44c

                 How do I fix this?

                 And is this a "bug" in the Live ISO?

                 Many thanks,
                 -T

        Hey have you managed to solve your issue already?

        If not try unchecking the box that says "Change the background" and
        checking the box "Apply to all workspaces"

        Hope that helps,
        Roman

    Hi Roman,

    On my VM, "Change the background" woke and unwoke my ability
    to change the background directory.

    On the machine in question, no joy.

    I think there is some corruption or something.

    Do y9 know how to set this manually (vi)?

This, although from 2008 may be helpful:

Check ~/.config/xfce4/mcs_settings/desktop.xml

Or that directory for settings related to the background.

If it's not there, maybe, just maybe ~/gtk-2.0 or gtk-3.0

You may also want to try installing "mlocate," and use the 'locate'
command with "wallpaper" or "background" and see what comes up for
config files

Hi Roman,

I have been using "find . -exec grep -l xxx {} \;" to try and
find where the setting is kept, but no joy.

This is my xfce4 config directory:

$ ls -al .config/xfce4
total 0
drwxr-xr-x.  6 tony users  61 Mar  4 01:29 .
drwxr-xr-x. 10 tony users 162 Mar  4 12:52 ..
drwx------.  2 tony users  72 Mar  5 18:34 desktop
drwxr-xr-x.  7 tony users 100 Mar  4 01:30 panel
drwxr-xr-x.  3 tony users  33 Mar  4 01:28 xfconf
drwx------.  2 tony users   6 Mar  4 01:28 xfwm4

No sign of "mcs_settings" on either the function or
the non-functioning machine.

$ find .config/xfce4 -exec grep -l -i desktop {} \; 2>&1 | grep -v direct

$ find .config/xfce4 -exec grep -l -i background {} \; 2>&1 | grep -v direct
.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml


xfce-perchannel-xml:

<property name="workspace0" type="empty">
          <property name="color-style" type="int" value="0"/>
          <property name="image-style" type="int" value="5"/>
          <property name="last-image" type="string" value="/usr/share/backgrounds/images/default.png"/>
          <property name="backdrop-cycle-enable" type="bool" value="true"/>
        </property>

Not finding a "path" or a list of backgrounds.  Just the last
background used.

So, who knows.
