I'm not sure if this is the same bug, but neither lightdm or gdm will start a session for me. For both lightdm and gdm with any kind of session (unity, unity2d, classic, xfce ...) the gui dies and flashes what was on console 7 and then restarts. My only way in is console 1 text login, stopping lightdm and running startx.
It happened about not quite 2 weeks ago - I am running 12.04 beta. I had hoped the 12.04 release would fix it but no dice.
