I am running Ubuntu 16.04 LTS on a Dell I5555 with a radeon card. This
started happening after a few successful boots in graphics mode. I
suspect, although I am not sure, that it started after I needed to
install an extra library for a package that I had installed. But BEFORE
that, in order for the system to boot at all, I had to enter the
"nomodeset" option in /etc/default/grub . Without that it did not let me
get past the point where it complained about the lack of UMS support on
my radeon graphics module. Removing the "splash" option helped me to
then enter the encryption password and boot in text mode. The extra
installations that I needed to do, which may have broken the boot [i.e.,
my ability to enter the encryption key password in graphics mode] are:
the libicu52 library, which, in turn, required xcb - and that then
wanted xcb-proto . It may be worth checking what these graphics
libraries do to influence a boot in graphics mode.

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.
