Thanks @goingwc, I have managed to reproduce it here so I can use my own plymouth log. Turns out I couldn't get even 18.04 working correctly, because I had integrated GPU enabled in my motherboard settings (i7-6700K with HD 530) despite nvidia being set to "primary GPU". I had to disable the integrated one completely.
After doing some experiments I noticed that this is not related to nvidia, but to modesetting - I was able to reproduce this issue without nvidia drivers installed, just by adding nomodeset to kernel cmdline on pre-bionic releases (tested on Xenial and Artful). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-384 in Ubuntu. https://bugs.launchpad.net/bugs/1721988 Title: Ubuntu 17.10 full disk encryption + Nvidia drivers not booting Status in nvidia-graphics-drivers-384 package in Ubuntu: Confirmed 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).
