Tried 3.14.0-031400rc5-generic mainline kernel but the bug is still happening.

But I'll keep working on it. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1284296 Title: screen blanks (as if computer is off) after grub but only sometimes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1284296/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
