I have the same behavior after upgrading from Ubuntu 13.04 to 13.10 this evening on my Asus UX31A: blank screen and can not get into a terminal. I tried booting from a USB drive with the 13.10 x64 image and got the same result.
I found this forum post (http://ubuntuforums.org/showthread.php?t=2175602) which suggested booting with the 3.8 kernel from the GRUB menu, and everything works fine. I'd be happy to submit logs if someone can let me know which logs are needed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1229686 Title: No video output at all when booting 13.10 on Asus Zenbook UX31A Status in “linux” package in Ubuntu: Confirmed Bug description: After upgrading to 13.10 from 13.04 my computer booted into a black screen. I could hear the login sound but couldn't see anything. Switching to some virtual console isn't working either, nor was anything visible during the boot process. I also tried to boot 13.10 from USB with a very similar result. The IGP of the Zenbook UX31A is the Intel HD4000.
