Title:
  Lubuntu vivid amd64 2015-01-28 does not boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Lubuntu vivid amd64 2015-01-28 does not boot on a MacBookPro from USB
  stick.  I put in the USB stick an hold down alt while powering up the
  computer.  Then the choice of boot media comes up, and I select the
  USB stick.

  Here  are the hardware specs

  http://linux.slashdot.org/story/15/01/28/1520252/why-screen-lockers-
  on-x11-cannot-be-secure

  Here is the image which does not boot:
  http://iso.qa.ubuntu.com/qatracker/milestones/326/builds/88376/downloads

  The image starts in "insecure mode" and then GRUB comes up and offers
  several choices.  When choosing "Try Lubuntu without installing" it
  runs for a few seconds and then  freezes, apparently indefinitely.
  There is no way to get to another console with ctrl-alt-f1 or anything
  else.  The only text on the console is:

  [    7.093063] i i8042: No controller found
  starting version 218

  More or less the same error occurs when choosing "Install Lubuntu"
  from GRUB

  What should have happened is that the installation proceeds or else
  the Live session starts, depending on the choice in GRUB.
