Public bug reported: 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_signature Ubuntu 3.13.0-12.32-generic 3.13.4 $ 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://ubuntuforums.org/showthread.php?t=2207624. I'm not sure if the computer has crashed or its simply not outputing video, but the only way to recover is to do a hard restart and cross my fingers that it wont happen next time. 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?).
