Comment 51 for bug 1364630

  Most of this is way over my head. Man, do I envy and admire all you who are light years ahead of this 59 yr. old who never touched a computer until a few yrears ago. I'm posting this for the many newbie users out there like me.
  I too was getting the "init: Error while reading from descriptor: Broken pipe" error in Lubuntu 14.10 with Nvidia GE 7300 Force using the recommended Nvidia 304 drivers (I got the error most of the time- but not always- although the boot always completed and I was always able to use the machine with no other errors).
  It just bugged me enough to start researching the error. I've read all the posts above and I'm really confused now. From the posts it seems the concensus is that its not necessarily Nvidia-related, but I decided anyhow to revert back to the basic Nouveau drivers...just for giggles and kicks.... the error is no more, and Lubuntu still seems to be flawless. Hmmm.
  Maybe this will help someone who gets the error and can't even get their machine to boot. Worth a try.
