[Bug 1386005] Re: Password not accepted graphical boot for encrypted root system

[Ondrej Balaz]

I am affected by the very same bug in 16.10. I have hybrid
virtual/dulaboot system - a physical encrypted partition + dedicated ESP
that is bootable on bare metal from UEFI and able to load either Ubuntu
or Windows; or bootable via VirtualBox using dedicated ESP and UEFI
boot.

- In case of bare metal everything boots properly and password can be
entered

- In case of booting in virtualbox boot stucks in LUKS password phase.
Any attempt to type is immediately echoed in text-mode over Plymouth
graphical screen (top left corner) and submit with enter doesn't work.
If I edit kernel GRUB's Ubuntu entry and remove these specific lines:

load_video
gfxmode ...

and remove following from kernel commandline: splash $vt.handoff

it boots in text mode, I am able to enter keyphrase and it boots just
fine.

Bug description:
  After upgrading to 14.10 from 14.04, I am unable to enter my password for decypting the root filesystem.  The password is echoed in plaintext on the  graphic boot screen and does not show up in the password entry box  on the graphic.   In order to boot the system, I have to boot in recovery mode and enter the password during the text mode boot.  This problem was also described by another user in problem# 1385027.   I did not have a probem in 14.04.   I am using nvidia drivers.   I am set to resolution 1920x1200.  I am running module uvesafb with changes to /etc/default/grub for the module and resolution.  I assume this is a plymouth package bug but am not positive.
