Now I tried Alt-F7 and had half a second of something looking very much like enlightenment--and then the screen went black again, including all VTs.

enlightenment_system implements privileged actions so enlightnement
doesn't need root to e.g. shutdown the system.

enlightenment_fm implements the file manager.

This is usually the most useful info.

This output shows that X has detected five outputs, and only one (LVDS)
is connected.

Do you have the lid closed on your laptop?  I wonder if it's running on
the closed laptop screen.  The later output about screen configuration
only shows actions for LVDS.

Since other windows managers are able to start X normally, it might be
useful to see if you can start one yourself:

1) From a VT run `startx xterm` (or whatever terminal you use).
2) Assuming X starts correctly, you should see a terminal in the top
left.
3) Move the mouse in the term and run `enlightenment_start`.
