Title:
  Blank screen after boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The screen becomes black blank between BIOS screen and the login page.
  The black screen never goes away. This is random not after install,
  update or upgrade. Also after PC reboot it works fine, it is not
  persistent problem, once PC is loaded it works.
