Honestly, this does not sound like a software problem, but a hardware
problem with your monitor.  When you turn your monitor on, do you also press
a key on the keyboard, or move the mouse, to unblank the screen?  (Nearly
all modern monitors will support DPMS to put the monitor in power-saving
mode when idle, so the screen will be black until woken up by some activity
from the computer.)  If pressing a key is not enough to wake up the monitor
reliably, then you may have a bad monitor or monitor cable, or a bad video
card.  If it's a software problem at all, it will most likely be a problem
with the driver for your video card.

Title:
  plymouth in Ubuntu, flashes log in than screen goes black

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  After waiting for months, I recently downloaded the offered Plymouth upgrade from the Software Center.  It's
  been about 10 days later.  Running Ubuntu 12.04.3 LTS

  Problems started yesterday,  I had some trouble with Plymouth about a year ago so I waited for months to 
  download the new upgrade with hopes that there would be no bugs. I'm a granny who just loves Linux but
  when I researched the problem there were too many different scenarios for me to know what the right fix was. 
  Thanks ahead for any help and energy on my issue!

  I booted up my PC to only see a black screen. I pressed the on/off button for monitor and got my log-in screen
  back, logged in and was alright.

  This morning, I booted and got black screen, using on/off on monitor didn't work this time. I logged in with the black
  screen on, got in but screen went black again. I used the on/off of the monitor, screen stabilized and function returned
  to normal.

  Looking at the changes from yesterday to today, I am concerned that soon I may not be able to get booted in at all, if
  things continue to deteriorate . I have a NVIDA card which I see from my troubleshooting research can have trouble
  with this Plymouth issue and/or the offered drivers. The PC is a Dell OPTIPLEX 760. ( wish it was newer)  I 

  I am good at following instructions so if you have a fix for me please
  let me know what I need to do. Thanks!!
