Public bug reported:
When I logged into my computer today, Unity wasn't showing my wallpaper.
The first thing I tried was to go into the Appearance settings and
change the wallpaper. At first, I was not able to make any changes to
the wallpaper. Then I started tinkering around with dconf, just to see
if I could find any settings that might interfere with the wallpaper.
What I found was that /org/gnome/desktop/background/show-desktop-icons
was set to false, but if I set it to true, then the regular Appearance
settings panel was able to change the wallpaper. and again, if I set it
back to false, then I was no longer able to change what wallpaper is
used.
Steps to reproduce:
1. Using dconf, set /org/gnome/desktop/background/show-desktop-icons to
false
2. Using Gear menu -> System Settings -> Appearance, try to change the
wallpaper. You can't.
3. Set show-desktop-icons back to true.
4. Change the wallpaper now -- it works.
So, this is quite strange to me -- turning on show-desktop-icons doesn't
actually render any icons on my desktop. It only enables the wallpaper
switching to work. My best guess as to what is happening here is that
"show-desktop-icons" really just means "make nautilus render root
window", and somehow I've stumbled onto a bug by which g-s-d can no
longer render the wallpaper for itself, so turning on show-desktop-icons
forces nautilus to take over, where it is successful in rendering the
wallpaper.
Let me know if there's any additional information I can provide, and I
will happily cooperate in troubleshooting ;-)
