Public bug reported: Booting without the nomodeset or i915.modeset=0 results in a complete system lockup during boot. This has increasingly been happening in the later versions of Lubuntu 14.10, but after upgrade to 15.04 has become permanent.
The only way to start is using the nomodeset or i915.modeset=0 settings, which reduces the resolution which can be used.
