Title:
  Ubuntu 12.04 doesn't start on Dell Inspiron 15z laptop

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  When starting up from the grub loader, if kernels 3.2.0.35, 3.2.0.34,
  or 3.2.0.33 are selected, startup does not appear to occur.  Instead,
  the screen stays blank (completely unlit), but the machine is on.
  Startup occurs normally with 3.2.0.32 or earlier versions.

  Using Ubuntu 12.04.1 LTS.

  WORKAROUND:
  GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq acpi_backlight=vendor dell_laptop.backlight=0 quiet splash"
