[Carl Miller <chaz@xxxxxxxxxxxxxxx>]

Hi, Christopher.  Thanks for all the helpful links!  Indeed, I applied
the BIOS update, and the hard freeze is now gone!  It's not all working
exactly as I expect, but at least the BIOS change cured the worst
symptom.

Changes made:
Applied MSI BIOS update to version 71D.
Changed light-locker back to activate on screensaver activate.

New behavior when coming back to laptop with locked screen:
Make a movement on the touchpad.  Screen remains completely black, BUT computer is still running properly, as shown by network traffic.
Click the mouse buttons.  Same thing, screen remains completely black, but no hard crash; everything is still running.
Press some non-typing keys (shift, ctrl, etc.).  Same thing.
Blindly type my password into the completely black screen.  Screen turns on, unlocks, and shows me my full working X environment, exactly as I'd left it.

Which is at least usable.  Not ideal, and not what I think is expected
behavior, but behavior I can deal with.

Title:
  Freeze on screensaver deactivate when set to lock on screensaver
  activate

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  A few months ago, I started having a problem where my laptop would
  freeze and require a hard reboot when I tried to wake it from
  screensaver.  I tried turning light-locker off; this fixed the
  problem.  However, now due to company policy, I have to turn light-
  locker back on, and found that the problem still existed.  After some
  searching, and trying different things, I've found that if I set
  light-locker to activate on screensaver *deactivate*, then everything
  works properly, and when I wake the laptop from screensaver, I'm
  presented with a blank X background and password dialog.  If I set
  light-locker back to activate on screensaver *activate*, then my
  computer continues to run until I press a key or touch the touchpad,
  at which point it freezes.

  Note, I keep suspend and hibernate turned off completely on this
  laptop, and almost never run on battery.  The above happens when
  plugged into AC power.  It would appear to be purely in the realm of
  light-locker and the screensaver.
