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).
