Comment 9 for bug 45107

This seems to be caused by the xorg intel video driver. I experience the bug on a laptop with two video cards: one is an Intel i915 and the other is nVidia 6600GT. If I start the laptop with nVidia switched on, the autologin works as expected. If I boot it with the internal i915, the autologin won't work.

(My guess is, that it relates to intel driver autodetection procedure, which restarts X in a similar way ctl+alt+backspace would do - in that case, autologin wouldn't work, which would be expected behavior. I think it might be related, because my screen blinks during boot, revealing one of the VTs with init information in one point)
