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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721988 Title: Ubuntu 17.10 full disk encryption + Nvidia drivers not booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-384/+bug/1721988/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
