[Bug 1359689] Re: cryptsetup password prompt not shown

[Maciej Jesionowski]

Adding my experience in case someone has the same issue.

Installed a fresh Ubuntu 16.04.3 with the clear entire drive and set up
LUKS+LVM option. After the first reboot I got the graphical password
prompt but couldn't type anything. After the next reboot, after passing
GRUB, the screen just stayed blank purple. Only ctrl+alt+del worked.

To get the system boot correctly I edited the default GRUB Ubuntu entry
(the 'e' key in GRUB):

1. change the line "gfxmode $linux_gfx_mode" to "gfxmode auto", or just remove it whole
2. remove the "splash" from the linux kernel cmdline
3. boot with F10

After that I got a text prompt to unlock my disk volume and after giving
it the password the system started normally.

If this works for you and you want to make it persistent, edit the
/etc/default/grub file (with sudo):

1. remove the "splash" from GRUB_CMDLINE_LINUX_DEFAULT
2. uncomment the line GRUB_GFXMODE and set it to "auto", GRUB_GFXMODE=auto
3. save the file and run the command "update-grub"

Hope this helps.

Bug description:
  Currently in utopic the following happens when booting an encrypted
  setup:

  Press enter in grub, after a while screen freezes (or turns completely
  black) and stays like that. When I press the down key, I can see the
  password prompt. When I press the up key again, I get to the graphical
  password prompt.

  This is demonstrated in the following screencast:

  Maybe this is related to the version of plymouth utopic currently uses, a similar debian bug report seems to be resolved with a newer version 0.9.0-6, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=752752.
