[Bug 2105377] Re: Plymouth doesn't show splash screen with NVIDIA GPU

Sun Mar 30 03:36:45 UTC 2025

This reminds me of bug 1869655, which may be worse on Nvidia systems if
there is no driver loading early enough.

It might also be because the boot GPU has been hidden. I can tell this
machine has two GPUs; Intel and Nvidia. But the Intel GPU is no longer
listed as a PCI device. Though that might not matter if the simple
framebuffer used during early boot is still available via BIOS
interfaces.

The Plymouth log suggests a combination of these issues:

  got add event for device /dev/fb0
  ignoring since we only handle subsystem graphics devices after timeout

and

  creating objects for frame buffer devices
  found device /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/efi-framebuffer.0/graphics/fb0
  device is initialized
  found node /dev/fb0
  device subsystem is graphics
  found frame buffer device /dev/fb0
  trying to find associated drm node for fb device (path: pci-0000:01:00.0-platform-efi-framebuffer.0)
  no card entry!

Please try adding this kernel parameter:

  plymouth.use-simpledrm

I'm guessing that will fix it and this will be a duplicate of bug
1869655.

Title:
  Plymouth doesn't show splash screen with NVIDIA GPU

Status in plymouth package in Ubuntu:
  Incomplete

Bug description:
  I just updated to plymouth 24.004.60-2ubuntu6 but even the splash screen is enabled, it doesn't show, just text during boot.
  I'm using driver 570.133.07-0ubuntu2. When I was using versiong 570.86.16-0ubuntu4 the splash screen worked as should.

  This bug is a spin off of https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/2103533, where Daniel asked to create a new bug report about it.
