+ prompt with certain hardware, unless they switch VTs to toggle the video
+ mode.

  When booting the plymouth splash screen is shown for a second and then the screen goes blank.
  I have an encrypted the root partition so this makes it a bit difficult to input the password.
  Entering the password after some time when the screen is blank works fine though.
  
  Switching the VT with ctrl+F6, ctrl+F7 shows the plymouth password promt
  again but it's very distorted.
