[Bug 1546393] Re: boot in xenial shows black screen instead of plymouth logo / encryption prompt

[Francisco Angel Javier Prieto]

Well, I executed Grub Customizer.
I'm check Custom Resolution and select 1024x768x24 and then Save.
If I reboot Show up the prompt, but the keyboard usb hang.
If I turn off and turn on show up the menu and the prompt in text mode. This is my grub now:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

#   info -f grub -n 'Simple configuration'

Title:
  boot in xenial shows black screen instead of plymouth logo /
  encryption prompt

Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  After updating to xenial, I see nothing but a black screen after EFI
  boot successfully.  I can blindly type my disk encryption password to
  get the system to evenutally boot to a GDM prompt, but there's no
  visual feedback before that point.  At first I thought it was because
  the initrd wasn't created properly on upgrade from wily
  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1546342), but
  forcing it to regenerate by apt-get install --reinstalling the kernel
  didn't fix it.
