Hey, I have this problem since a while but it got a lot worse with the last two kernel versions. Now there's an about 50/50 chance to see the user login or simply not see it. I don't have any login manager set up, so after boot there's simply the user login and after that I issue startx. It all works just fine,even if I can't see a thing, and once I issued startx everything goes back to normal, the screen isn't blank anymore.
The machine has an Intel chipset, and I guess it's related to that and/or KMS, but that's as far as my guess goes.
Maybe one of you knows something about that kind of issue?
You need to save the dmesg output of a failed and a successful boot and compare them. Note that the DRM/KMS driver seems to initialize fine - otherwise, starting Xorg would fail entirely (Intel's Xorg driver depends on it).
