Title:
  black screen boot

Status in ubiquity package in Ubuntu:
  Expired

Bug description:
  I have just install Ubuntu 20.04 in a pc with Windows 10. I have used
  an usb stick. Before the welcome window emerged the screen went black
  with white letters completely frozen. Then I pressed the power button
  (one or two quick presses) ans suddenly the welcome window emerged.
  All the installation seemed to be fine. But when I restarted and I
  have chosen "Ubuntu" in the first menu that has appeared when I
  started the computer (I could choose between "Ubuntu", "Advanced
  Ubuntu", "Windows" and "UFI Firmware") and then the screen went mostly
  black with purple and green lines. Then I pressed the power button to
  quit (two quick presses) and suddenly I could have access to my
  account and then everything was normal. I have tried many times and
  always it's the same. I also have found another way to skip the black-
  green-purple screen going to "Advanced Ubuntu", then "Ubuntu recovery"
  and then "normal boot". If I do it this way everything seems fine and
  I skip the frozen blac-green-purple screen. What should I do to fix
  it?

  So sorry if is confusing, I'm new in all of that and my English isn't
  good. Thanks very much.
