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

[Rgpublic]

I'm unsure if this is exactly the same issue, but, yes I still have the
issue that my password is not accepted if I just enter it on the
password prompt and press Enter. What I figured out so far is that the
problem seems to arise from the fact that my password starts with a
capital letter. During Ubuntu installation the installer happily did
accept the password, though and didn't complain that a password must not
start with a capital letter or anything.

Now, when the system boots, I see the graphical plymouth password
prompt. As soon as I press the shift key to enter the first capital
letter of my password, plymouth disappears :-( And, weirdly, even though
I pressed only the shift key, 4 letters already appear behind the text
password prompt that I didn't type!? Because they are asterisks I don't
know what letters they are. If I backspace them and enter my password,
the system boots. If I just enter my password without backspacing, then
the password is not accepted. Probably because it's prefixed by those 4
mystery letters that have been typed automatically.

Another workaround is to first type a lower case letter while the
graphical screen is still on. Then backspace that and enter the real
password. This will keep the graphical bootscreen.

Only problem: This is quite difficult to explain to some family members
who get very easily confused by this... :-/

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.
