I could fix this on my computer like this: Summary: In /etc/default/grub, I edit the options so that plymouth is not used.
Details: sudo nano /etc/default/grub Then: edit the following parameter to the new value noplymouth GRUB_CMDLINE_LINUX_DEFAULT="noplymouth" After that, you must run update-grub: sudo update-grub Result: Plymouth is not used any more at startup and you can enter the passphrase in text mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385027 Title: You broke the encryption password screen at boot.
