Might be helpful or not, thought I'd just drop it here.

After installation of a fresh Ubuntu 13.10 with Secure Boot (and with
CSM Disabled in the BIOS), using an internet connection to get updated
packages, booting with nomodeset and installing nvidia-prime, I find
that X/lightdm works pretty well. I can even activate desktop effects
and the whole thing runs very smoothly. However, many features are
broken (can't get an extra screen plugged in, can't suspend to
RAM/Disk).

Not sure that's relevant information, but it can't hurt.

Title:
  8086:0a16 [ASUS Zenbook UX302LG] Black screen on boot

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Install via LiveUSB created with unetbootin off the saucy amd64 iso
  was able to be completed with "nomodeset". First boot into installed
  system resulted in lightdm "cowbell" being played but a backlight on /
  blank screen on the display. using nomodeset on installed system
  results in framebuffer/console being usable - but no X able to start
  (cannot find screen). tried some alternative kernel options :
  acpi_backlight=vendor, video=1920x1080-24@60 but with same results.
  Tried using different kernel as per bug
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1195483 . pinned
  and upgraded to trusty kernel images - slightly different result in
  that backlight goes down and breifly have a red screen tear in upper
  left of screen for several seconds before reverting to same behaviour
  as saucy kernel. (blanked screen, backlit, lightdm cowbell plays).

  WORKAROUND: Upstream drm-intel-next build resulted in working lightdm/screen:
