For what it's worth, I am having the same issue (I think). Cannot enable desktop effects at all: results in screen corruption as described in this thread, then automatic restart of xorg and login screen without effects enabled. If I force UXA I get the screen corruption from the outset. This on a Thinkpad T500 with GMA 4500 intel card.
