xorg - Black screen after upgrading from 13.04 to 13.10




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.
