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

[Scott Tawse]

I had 16.04 for 2 weeks on my newly built pc. The OS was running great
until today when I restarted my pc and wasn't able to type in my
password as I usually would. Instead popped up in the top left of the
screen. Confused I start fiddling with everything I could and for the
next 3-4hrs nothing. At that rate I got desperate. Began asking around
due to not finding this similar problem anywhere and people began to say
I had ransomware. I questioned this greatly but panicked at the same
time. Then learned I could gain access through recovery mode. Though why
should I go through all this trouble to gain access to my pc? I then
resorted to wiping the ssd and restoring my files on a newly installed
16.04 ubuntu OS.This time without the encryption on boot up. Seems to do
some sort of low quality box shaped circles now on boot up but have
usual access to the pc now. In all honesty I want the extra encryption
but hate that this glitch is such a thing. Was then told that this has
been a ongoing issue for YEARS now. To think that such an issue like
this is still not fixed is insane. Hope though maybe soon this will
finally get fixed.

Title:
  Password not accepted graphical boot for encrypted root system

Status in plymouth package in Ubuntu:

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.
