Public bug reported: Since latest updates lightdm does not start any desktop environment. After loging in a blank screen (if you had set a desktop background the desktop background) is shown. No window manager, no session manager gets started.
To start a desktop environment you'll have to switch to a console (CTRL-ALT-F1). Login with your username and password. Give "sudo service lightdm stop". After lightdm is stopped you can start your desktop environment with "startx".
