[Bug 2072153] Re: LUKS/Cryptsetup shows blank screen on boot in noble

[Daniel van Vugt]

Are you using an external monitor or the laptop screen at boot time?

Please also try kernel parameter: plymouth.use-simpledrm

Title:
  LUKS/Cryptsetup shows blank screen on boot in noble

Status in plymouth package in Ubuntu:
  Incomplete

Bug description:
  After upgrading from Ubuntu 23.10 to 24.04, I get a blank screen at
  boot instead of the password prompt. I can enter my password blindly
  and boot into X as usual, but nothing I have tried for getting the
  password prompt has worked.

  I'm on a Thinkpad T580, with an NVIDIA GeForce MX150. I'm on the
  nvidia driver version 555.52.04 from the graphics drivers ppa.

  I have tried various combinations of:
  - not having driver version 555 installed (It was left at the old version on upgrade
  - modding grub to say nosplash, gfxmode=auto or gfxmode=text or gfxmode=wxh (all gave me text, but also a kernel panic about synaptics drivers)
  - modding grub to say nomodeset, and/or nvidia.modeset=0
