Public bug reported: Ubuntu 16.04 beta had some updates today. I installed the updates, rebooted, and logging in would never complete. When I logged in, my desktop would appear, but the dash, launcher, and titlebar would never appear. The problem resembled the issue reported here: https://askubuntu.com/questions/476930/ubuntu-desktop-does-not-load . I was able to right-click on the desktop and open a terminal (which was missing a titlebar).
I was able to work around the problem by running dconf reset -f /org/compiz/ gnome-session-quit --force and then logging in again. However, before I did that, I dumped all of my current dconf settings to a text file first. I've attached the text file dump of the /org/compiz dconf keys that caused the problem. Here's the diff between my old problematic dconf settings and the new ones after I reset them and logged in again. I would guess that the problem has to do with the plugins-with-set-keys or active-plugins settings referring to things that were removed in the update.
