[Bug 1500751] Re: Cryptsetup Keyboard not working on Xubuntu 3.19.0-30

[rolfinator]

So, I have a "fix" now in place, that is awful, but at least I do not have to boot, kill and boot again...
I edited /etc/default/grub and made the following changes:

I commented out the timeout for grub, in case I need to make some changes on the fly.
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false

But the more important line is this:
GRUB_CMDLINE_LINUX_DEFAULT=""

So I removed the "quiet splash". This causes no Crypt screen to appear,
but to go directly into "blackscreen-state" and therefore enables me to
enter my passphrase (although, I don't see if/what I am typing). If the
entered passphrase is correct, I see the OS.

Title:
  Cryptsetup Keyboard not working on Xubuntu 3.19.0-30

Status in Plymouth:
  New
Status in cryptsetup package in Ubuntu:
  New

Bug description:
  I am running Xubuntu 15.04 and just upgraded to the latest kernel (3.19.0-30).
  After upgrading the boot time is longer (what is negligible) but the more sever error is, that I cannot enter my passphrase when I see the crypt dialog.
  I just see the dialog to enter my passphrase, but when I try to enter it, nothing appears in the textfield. I tried with the builtin laptop keyboard but also with an external USB keyboard.

  I thought about supplying more information, but things like the syslog
  are not helping apparently (I was not able to boot until the syslog
  would capture information...). If you need anything I can provide, I
  gladly help.

  [Test case]
  1. On an affected system boot into kernel 3.19.0-30

  [Solution]
  The "solution" for now is booting the older Kernel 3.19.0-28 (which isn't a real solution).
