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

Given that you have uvesafb configured, I'm surprised to see that you
don't have anything in /proc/fb.  I wouldn't expect this to change as a
result of booting in recovery mode, since I don't think uvesafb is a KMS
driver and is therefore unaffected by the 'nomodeset' boot option.
Also, it seems you're passing 'nomodeset' even in your default boot
config.

If you disable the use of uvesafb in /etc/default/grub (by setting
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"), do you experience any
problems?  This is probably the most straightforward workaround for
right now.  It won't give you a graphical plymouth splash, but it also
won't force you to use recovery mode to boot.

Title:
  Password not accepted graphical boot for encrypted root system

Status in “plymouth” package in Ubuntu:
  New

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.
