Public bug reported:
No luks password prompt - plymouth
NON root LUKS block device encryption (no initram involved)
Bug 1359689 Ubuntu or Red Hat(!) Bugzilla – Bug 1086972 are still valid.
With Ubuntu 17.10 in November 2017 the problem remains:
It is a Plymouth issue, not an issue of LUKS or NVIDIA or Linux-distro.
Issue: I have an encrypted non-root-partition (actually /home) and the
whole lifecycle of booting, working, closing works flawless. Boot and
LUKS will handle the process based on crypttab and fstab, no entry in
inittab. Follows the (correct) specs and works well.
Except the password request.
Plymouth swallows the password request.
Here we do NOT talk about the initram issue - this is a slightly
different situation, same bug. So solutions for similar cases do not
work here.
Reproducible you can try to guess when the request should be there,
manually enter the matching password and the mounting goes on well.
Reproducible, when you prematurely press "enter" during(!) the checking
step the displayed lines shift up (and display an empty line). The
password request becomes visible in this empty line after finalised
checking procedure. Could probably be circumvented by adding more
newline characters, it seems.
So it is clearly a display issue caused by Plymouth.
The request for password is fired up correctly. It is just not visible
to the user.
I do not have a NVIDIA in the machines I implemented it in. It's
happening on laptop with Intel graphics as well as on a desktop with A10
APU graphics.
Graphics card does not matter at all.
I do NOT use the graphical / picture grub screen, rcS has extended
verbosity.
