If and once you get back up, a thread not long ago reminded me about
"free -m". I've had odds and ends of problems like this blank screen
myself over time.

That goes back to me at least once writing about how I was sometimes
forced to reboot fresh... then the last previous session would come
back up in its entirety, e.g. browser open with last used tabs, text
editor with last multiple accessed files, etc. That was NOT expected
behavior on a fresh reboot. :)

With "free -m", I'm seeing inconsistencies in what comes in and out of
SWAP after mine goes into some level of sleep/hibernation. Sometimes
it will clear out completely, and other times almost nothing exits.
That "almost nothing exits" part makes me wonder how that might affect
waking back up into full functionality *sometimes*.

That's on a desktop PC box. I don't know if SWAP's role plays a part,
but the inconsistencies I'm seeing reflected in mine felt worth
mentioning... :)
