Title:
  screen blanks (as if computer is off) after grub but only sometimes

Status in “linux” package in Ubuntu:

Bug description:
  First of all, I appologize if I filed this bug wrong, this is my first
  time. I am also not 100% sure it is Xorg related, but that seemed the
  most appropriate choice when I was anwsering the questions in the
  ubuntu-bug utility.

  $ cat /proc/version_signature 
  Ubuntu 3.13.0-12.32-generic 3.13.4
  $ lsb_release -rd
  Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04

  I originally tried to install 13.10 but had this intermittent blank
  screen problem so I hoped 14.04 would have a fix but it did not and
  now I'm troubleshooting in 14.04.

  The problem is intermittently after I select ubuntu from grub my
  screen will blank (no signal) as if my computer were off. Here is a
  link to my forum post discussing the problem and what I've done to try
  to resolve it http://ubuntuforums.org/showthread.php?t=2207624. I'm
  not sure if the computer has crashed or its simply not outputing
  video, but the only way to recover is to do a hard restart and cross
  my fingers that it wont happen next time.

  I know there are many bugs about blank screens, but this one seems to
  be unique in that it happens seemingly at random (race condition?).
