To add to this also happening to me, I do see the lock screen when I
open my laptop, and it's only then when I enter my password does the
screen go black.

Title:
  Black screen on resume in Xubuntu 14.04.1

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  It seems #1303736 is Not fixed.

  Black screen on resume when using standby on close lid is confirmed on
  Dell Latitude D400 on completely new install of Xubuntu 14.04.1 32
  bit. downloaded 14 Aug from repository as a .ISO image.

  This despite claims to the contrary on the website.

  settings/+bug/1303736

  Using the "Suspend" key results in correct operation, i.e. the laptop
  suspends and resumes correctly on lid open. Suspending by closing the
  laptop lid results in the black screen when re-opening. Once in black
  screen mode, the only recourse is power off re-boot.

  Although power manager is set correctly to "Suspend" in the power
  manager , on closing the lid the system does NOT appear to suspend as
  it does when the "Log-off Suspend" button is clicked or the hardware
  "Suspend" key is pressed i.e. the problem APPEARS to be on lid close.

  Power manager and light-locker set NOT to lock on suspend or shutdown
  makes no difference to behaviour.

  Xubuntu up to 12.04.4 (plus latest updates) worked absolutely
  correctly before new install of 14.04.1

  This is a MAJOR inconvenience for an upgrade of an LTS.
