Title:
  Dual monitor setup shows inactive screen as black rectangle at startup
  since update 20.04-22.04

Status in kubuntu-meta package in Ubuntu:
  New
Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  Setup; unchanged since 20.04 (where it worked):
  Laptop, screen 1920x1080, not enabled, set in configuration
  Monitor, screen 2540x1440, set as enabled, primary

  After start, login, desktop coming up, a black rectangle of the size
  of the disabled laptop screen appears in the upper left corner,
  covering the larger part of the desktop. After some 30 seconds, it
  disappears on its own.

  This happens since my upgrade 20.04->22.04; without any changes on my
  side w.r.t. hardware or settings.

  It doesn't damage anything, it is just a bore. But one that indicates
  an underlying problem: the disabled screen doesn't have to be laid
  over the enabled screen for some time. It should be off.
