Bug#976235: enlightenment: e switches off screen|monitor

[enno]

Package: enlightenment
Version: 0.24.2-5
Severity: important

Dear Maintainer,

Upgraded e, after that e on start complained in a window that I had no screen
configured to display on--but my 4 screens from prior .e were present.  But
the complaint persisted, so finally I tried the suggested Settings->Screens--
but that doesn't exist.  However I remembered there was some Screen config
somewhere, found that, didn't find anything to configure.  Complaint about
unconfigured persisted.  So again into the configure-dialog, there is a lot of
options without explanation or tooltip, f.i. one checkbox choice with
0 90 180 270 as choices.  Checked 90 and haven't seen e again since that.

Calling enlightenment_start since then just switches off the monitor (on a
laptop) and .xsession-errors contains some lines that google doesn't come up
with any solution:

flwm works--enlightenment is dead.  I suppose there is some unrecognized
dependency problem.
