Just a thought:

Were you perhaps playing around with SE Linux or GLX packages/settings when
the problem started occurring?
Did you switch kernels / kernel modules by any chance?


Otherwise the blacked out screen could indicate a wrong video mode, i.e. the
frequencies are outside the screen's capabilities and thus it blanks. But I
would not suspect X failing to launch in this case.
