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

[Andrew]

I reported this bug too and it was marked as a duplicate.  I thought I'd
add my description in case it helps.  I'm seeing some really strange
behavior, not as critical as it not booting at all, but it is counter
intuitive.  When I boot, the screen appears blank until I press the down
arrow key (regular keys don't seem to do anything), at which point the
screen shows a command line password box.  Pressing the key again shows
the regular gui.  This affects a fresh install of Ubuntu Mate 14.10.
Watch the attached video to see what I have to do each boot.

Title:
  Password not accepted graphical boot for encrypted root system

Status in plymouth package in Ubuntu:
  Triaged

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.
