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

[Jari Hyle]

I use ThinkPad T480 and I'm not sure if this particular instance uses
the Intel Corporation UHD Graphics 620 or GeForce MX150. The laptop is
connected to a Docking station. Docking station is "hinkPad Ultra
Docking Station" type 40AJ(or 4OAJ).

As this bug happens before I can get the drive unencrypted, is anything
written to logs?

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.
