  Computer does not return from lock normally

Status in light-locker package in Ubuntu:
  Confirmed
Status in lightdm-gtk-greeter package in Ubuntu:

Bug description:
  When I lock the computer from the whisker menu, the screen goes blank.
  It will remain blank even if I move the mouse, click or press keys.  I
  can get the screen back on with Ctrl-Alt-F1 for a command prompt.  Or
  Ctrl-Alt-F7 gives me large white text on a black background, saying
  "This session is locked.  You'll be redirected to the unlock dialog
  automatically in a few seconds."  And in a few seconds I do get an
  unlock dialog in a few seconds.  The system works normally thereafter.

  If I close the laptop lid while the laptop is plugged in, the screen
  is blank when I reopen it as above.  Ctrl-Alt-F1 works as above.
  Ctrl-Alt-F7 produces the "This session is locked" message, but it does
  not proceed to the unlock dialog.  This forces me to restart the
  computer.  Power Manager is set to lock the screen when I close the
  laptop lid.

  If I close the laptop lid while the laptop is on battery power, the
  screen is blank when I reopen it as above.  Ctrl-Alt-F1 works as
  above.  Ctrl-Alt-F7 has no effect.  This forces me to restart the
  computer.  Power Manager is set to switch off the display when I close
  the laptop lid.

  If is suspend the laptop from the whisker menu, on restore it behaves
  the same as locking the computer.  Ctrl-Alt-F7 allows me to get to the
  unlock dialog and continue using the computer.

  This is a System76 Galadro Ultra Pro.
