--- Comment #2 from James <james at nurealm.net> ---
After reading at Bug 76553 - "Dies on vt switch", I tried starting kmscon
without "--hwaccel".  That indeed avoids the "scrambled" display, I suppose
implying that the problem is EGL related.

As weston also fails to run from kmscon, the output now is:

Date: 2015-02-15 MST

That's a different issue, though.

If I start kmscon with both "--hwaccel" and "--debug", and then run "weston",
this also does not scramble the dispaly, though weston still will exit
immediately.  It's one of those "quantum" bugs - it's not there if you are
looking at it.  Ha!  Suggestions?
