I just installed the latest package upgrades pushed down for Xubuntu 12.04 (dbus and xslt package upgrades), and was told to restart the system. When the system came back up I logged in and instead of my own desktop background I had a solid color for my desktop background. I brought up Desktop Settings and saw that the app thought my own image was selected, but even after I closed the app I was still left with the solid color background. I went back into the app, selected another image, and then selected my own image again. Only now was the correct desktop image displayed. Has anyone else experienced this behavior? Does anyone know what causes it? Does anyone know how to prevent it from happening?
