[Bug 1852546] Re: Unencryption screen doesn't allow input after additional displays

[Jari Hyle]

Here's the output of journalctl -b -0

One thing to note though is that I found a workaround. When the screen
freezes I can used shift+tab to enter somekind of console and then
shift+tab back to the splash screen. Then it recognizes the additional
displays and I can enter the unlock code to the input bar again.

Title:
  Unencryption screen doesn't allow input after additional displays

Status in plymouth package in Ubuntu:
  New

Bug description:
  I'm not sure what package handles it as my researching skills are
  lacking.

  I have Ubuntu 19.10 installed with full drive encryption and when I
  boot up my laptop it asks for the unencryption key. If I power on my
  additional displays during that screen the keyboard doesn't input
  anything to the unencryption key field anymore. The keyboard works
  otherwise and I can ctrl+alt+del to reboot. Works normally if the
  displays are on from the start and not powered on during the
  unencryption screen.
