Title:
  Can't boot 14.10 LiveCD without "nomodeset" option - Macbook Pro 8.2

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  on Macbook Pro 8.2 (Early 2011 15"), and maybe some other models,
  if you will try to launch 14.10 Ubuntu LiveCD "as usual", you will be stuck at "i8042: No controller found" message

  (but this error message is not pointing to a particular problem which
  hangs a booting process --- because the same error message could be
  found at dmesg of successful booting with nomodeset option. it looks
  like the boot-breaking problem happens a bit later after an error
  message above)

  Workaround is to edit the booting option by adding "nomodeset", but
  such a step could be unobvious to unexperienced users. Ideally, if
  nomodeset option is really "must have" for booting some computers, the
  booting process should automatically check hardware IDs and detect if
  nomodeset should be enabled for the computer in use (at the early
  stage of booting) -- and user still would be able to remove nomodeset
  by editing the boot options, if there's a need
