Title:
  ASUS Zenbook UX302LG - black screen on boot

Status in “linux” package in Ubuntu:
  Confirmed

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).
