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_
Ubuntu 3.13.0-
$ 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://
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?).

Tried 3.14.0- 031400rc5- generic mainline kernel but the bug is still happening.
It crashes sometimes before sometimes after modesetting but always before plymouth splash screen (purple ubuntu screen).
I don't know what else to do to troubleshoot this problem. But I'll keep working on it.
