[emptythevoid <1207378@xxxxxxxxxxxxxxxxxx>]

This problem is most definitely caused by faulty hardware.  It's either
caused by the motherboard, or more likely, the video card.  My M6500 has
both Windows 7 and Ubuntu 13.10 on it.  With the FX2800 card, black
screens on boot-up/wake-from-suspend were somewhat frequent, but
eventually levelled out after a few reboots, on both Ubuntu and Windows
7.  I swapped the FX2800 card with a used FX3800 card and it's *worse*.
However, I'm able to use a setting in Xorg to tell the nvidia settings
driver to *always* throttle back the power mizer to a lower level, and
it works fine in Ubuntu.  Windows 7 doesn't have a good way of
permenantly setting this, and it goes to the black of death waaay more
than it did on the old card.

In any case, it's definitely a hardware problem of some kind, and there
is a workaround for it, but it's still crap.

Title:
  Screen intermittently goes black

Status in “nvidia-settings” package in Ubuntu:
  Confirmed

Bug description:
  This is a completely new build of 13.04 and after package updates the
  nouveau driver caused the screen to be a checkerboard of white and
  black squares after each reboot.  Instead I installed the nvidia-
  current drivers and Xorg displayed great, but now the screen often
  just goes black while working.

  This is happening when I had openSUSE installed as well as my current
  Ubuntu 13.04.  This laptop is 3 years old and it has worked
  wonderfully until now.  It's a Dell Precision M6500 and at first I
  thought it was a hardware issue, and Dell has replaced the
  motherboard, daughterboard, video card and hard drive, but the same
  issue is happening.

  It has taken at least 10 reboots just to get far enough to file this
  bug.
