Comment 8 for bug 1370707

I'm seeing this too, and I find it very annoying, because the screen goes blank long enough to make my monitor power down, and it takes over ten seconds to power back up when the video signal is returned.

So, I added "plymouth.debug=file:/var/log/plymouth-debug.log" to the kernel command line, and the result is attached. It seems that for some reason plymouth can't show the graphical splash screen, so it tries the text splash screen instead, but that isn't shown either. What can I do to debug this further?
