After upgrading to Ubuntu 13.04, the desktop wallpaper is gone in gnome-shell (however, the issue is occurred in Unity for some user). The issue seems occurs in the default setting of Ubuntu because my Gentoo box has no such problem with gnome-shell 3.6 installed. There are several ways to fix the issues with this reference: Desktop shows a white or black background instead of wallpapers.
- Use gnome-tweak-tool. In the Desktop category > Turn ON the Have file manager handle the desktop option.
However, it will cause the icons shown on desktop. If you do not want the icons, rollback option 1 and try the next option.
- Use gsettings to turn on/off specify feature. Try
$ gsettings set org.gnome.settings-daemon.plugins.background active true
. And it should display the wallpapaer with no desktop icon after re-login.
- Just install the latest gnome and gnome-shell through ppa. As reference: Fix – Ubuntu 13.04 background is white and no wallpaper.
# add-apt-repository ppa:gnome3-team/gnome3
# apt-get update
# apt-get install gnome-shell
Now I’m done with option 2. Maybe on day I’ll try option 3 for the latest version of gnome-shell. Enjoy it. 🙂
