Ok, it sounds more like there could be a crash behind the scene and everything stops working. On the text console bit I was a bit unclear. What I meant was to switch to text right from the start and do the login on the text console and also play around while being in text mode. If it crashes then, there is a better chance that you see what is crashing. If it does not crash or lock up it might be a hint that the bug might be in the graphics driver stack.
