Black screen after upgrading from 13.04 to 13.10 [closed]

Just upgraded from 13.04 to 13.10 and all I got was a black screen. The hardware I'm running is Asus Zenbook UX31A (Intel GPU).

I do hear that the login screen drums do play, so the system does boot to login screen. When I try to boot using kernel 3.11.0-12 recovery mode, it tells me "initctl: event failed". Then if I go on an press ctrl+alt+f2, log in and command startx, it dies because "Fatal server error: no screens found". Here are some logs from /var/log/Xorg.0.log http://pastebin.com/ZQasUKJx

Kernel 3.8.0-31 work ok, as did things before the upgrade.

It's a kernel bug, as reported here:

Quick solution is to switch to BIOS mode instead of UEFI mode.
= Disable Secure Boot and enable "Launch CSM".

You can peruse the Archlinux thread above if you want a more permanent fix and you feel like patching the kernel yourself. I don't consider myself technically good enough to do that safely (or quickly), so I'm putting up with running in BIOS mode for now and waiting until another Kernel is released.

It is a known bug ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1229686 ) with medium priority (althought this bug leaves the system unusable for people). If you set your system as affected in launchpad you will get status updates regarding this issue.

Set the compatibility mode (as mentioned by user203894) is one solution or just use an older kernel (max 3.9.9).
