Hi @dgadomski
Yeah, in a new installed version of Kubuntu 17.10 there is NO problem if the 
full-disk encryption is not ENABLED, however it also works if you do not 
install the Nvidia drivers for Kubuntu. This problem occurs when you decide to 
install Nvidia drivers for Kubuntu (as in my case) and have to set add nosplash 
for it to show the prompt to write your password before booting the OS.

If the user decide to set splash (GUI, to prompt password) then a black
window will appear or you can not write the password or any character
into the password prompt.


How can I as a user help Kubuntu to solve this problem?

Title:
  Ubuntu 17.10 full disk encryption + Nvidia drivers not booting

Status in plymouth package in Ubuntu:
  New

Bug description:
  I've installed ubuntu 17.10 with full disk encryption and then
  installed the nvidia drivers (v 384). when I boot the computer I will
  get the graphics interface to enter the encryption key but the system
  will stop to work, like it has hang. Basically I'm not able to enter
  the password!

  I've to restart in safe mode to be able to enter the password for the
  encryption, after that I can just resume the boot and all works.

  There seems to be some issues with the initial boot screen and nvidia
  drivers... I'm not able to press any combination of Control+Alt+Fx key
  to get any extra info about what is going on (not able to get any text
  mode).
