I believe the black screen is in fact a running xserver that has no
display manager no window manager no desktop and thus nothing to
display. Recommend you emerge your favorites.
Alternate run:
X -retro to start xserver that will show the old black/white stipple and
a mouse cursor.
Note: you will have to do a power off to get out of X.
