[emptythevoid <1207378@xxxxxxxxxxxxxxxxxx>]

I have a similar problem on my Dell Precision M6500.  Runnign 13.04,
with binary nvidia driver 331.20.  It mostly seems to happen after I've
turned the computer on and logged in, OR after waking from suspend.
Computer will work for some undetermined length of time (a few seconds
to a couple of minutes) and then the screen will go black.  The computer
seems to still be running, because I can see hdd activity.  And when the
screen goes blank, even the backlight shuts off.  The computer will not
repond to REISUB, and the only solution is to use the power button to
power it off and back on.  Sometimes, after this, it'll freeze one or
two more times before becoming usable.  It's done this since 12.04.

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.
