Bug Description

Running Xubuntu 14.04 with xfdesktop4 (4.11.6-1ubuntu1)

What happened: From within Ristretto (desktop set as Xfce in ristretto properties), I select View >> Set as Wallpaper, the desktop wallpaper doesn't change.

Expected: Desktop wallpaper will change.

Further Info: Running "xfconf-query -c xfce4-desktop -m" returns the following:

- when trying from within ristretto (doesn't work):
set: /backdrop/screen0/monitor0/image-style
set: /backdrop/screen0/monitor0/color1
set: /backdrop/screen0/monitor0/color2

- when trying from thunar (works):
set: /backdrop/screen0/monitor0/image-path
set: /backdrop/screen0/monitor0/image-style
set: /backdrop/screen0/monitorLVDS-0/workspace0/last-image

Interestingly, on my laptop, in xfconf, I have screen0 defined and 4 monitors underneath this screen:
- monitor0
- monitor1
- monitorLVDS0
- monitorLVDS1
...though I've never attached an external monitor. Laptop has an nvidia card using the proprietary nvidia driver.

Looks like the proper xfconf settings aren't being hit in this case.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/Xfce. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

In situations where there are more than one /backdrop/screen0/monitor entries, and the first entry is _not_ the valid entry, Ristretto does not change the wallpaper for that monitor property. It only affects the first entry. The end result is that the desktop wallpaper is not changed.

I have seen this in two separate scenarios:

1. Xubuntu 14.04 as a Virtualbox guest. On install, the /backdrop/screen0/monitor0 property is created. When the virtualbox additions are installed, a second property, /backdrop/screen0/monitorVBOX0 is created. The second monitor property is the active one, but Ristretto only affects the first monitor property.

2. Arch Linux install with nvidia driver. On install, the /backdrop/screen0/monitor0 property is created. When the properietary driver is installed, a second property, /backdrop/screen0/monitorLVDS0 is created. he second monitor property is the active one, but Ristretto only affects the first monitor property.

Changing the wallpaper from within xfdesktop-settings works, so that module must know which is the active monitor. That same code should probably be used here.

Currently I use this patch, in order to define new wallpaper.

Note: color1 and color2 properties are not supported.

- Use same value (stretched) for /backdrop/.../image-style
- Don't force to create /backdrop/single-workspace-mode property
