I am using Xfce 4.8 on Ubuntu 12.04. Any choice of Desktop Environment starts Xfce. I don't get any Splash Screen nor Xfce session selector nor WiFi icon, neither the option to restart/shutdown.
Last night I closed the session normally and today I found many problems:
- No matter whether I try to start session on Unity, GNOME, Gnome-Classic, MATE, etc, it always start Xfce. It doesn't even show the Xfce session selector nor the splash screen. 
- It doesn't start the - freemeteoscreenlet.
- Oragestarts up automatically.
- WiFi icon is missing (but I'm connected to the net). 
- On the user menu, "Suspend" and "Shut Down" are greyed out. 
- "Logout" is enabled, but when I click on it, it gives me the following error: - The name org.xfce.SessionManager was not provided by any .service files 
EDIT: The last package I had installed before this started was xfce4-utils. I can't open Synaptic Package Manager to uninstall it or to find broken packages. Synaptic doesn't start.
I don't know what to do. I'm still new to Xfce. Any ideas?
