I have the exact same issue with the laptop...
Tried the mainline kernel at http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty/ but the behaviour was the same as with 3.12 : black screen on boot.
Had to revert to 3.13 drm-intel-next and it worked OK except when screen is dimmed the laptop is lost and you need to reboot.
Also tried installing nvidia-331 but to no avail, black screen on boot but sortof cycling between on/off.
