I have also encountered this problem. After upgrading Wheezy to Jessie, I tried logging in from gdm3 to the new Enlightenment environment, but the screen first goes blank, then comes back with the standard background and pointer, but I cannot do anything from there. The pointer "flashes" when I press a mouse button, but nothing happens. I tried stopping gdm3, logging into a command console, and starting with "startx enlightenment_start". I was successful several times, but recently, this only gives a blank screen with nothing.
