odd issue booting F19 with LUKS partition

[Fred Smith]

hi gang!

I've put F19 on my Acer Aspire One (dual-core Atom) where it mostly runs
just fine.

but I've noticed one oddity (by no means a show-stopper) during boot:
when it prompts for the LUKS password (for the encrypted /home partition)
the box for password entry flashes on the screen, then the screen goes
blank for 30 seconds (or so) then the box appears again.

I noticed a day or two ago that if there's a bright lamp shining on the
screen when it is in that blank state that the box is in fact still drawn
there, but it appears that the screen backlight has been shut off--I can
still see the image of it faintly in the bright light.

Everything else regarding screen behavior is fine, but this one is
pretty consistently occurring every system boot.

This did not occur immediately after installation, but I first noticed
it only a week (or so) ago (sorry, I wasn't taking notes...) so one
wonders if some update has caused it.

Any ideas on this one?

Thanks!

Fred
