Thanks, yes, you added it correctly and that's the logfile we're looking
for.

This particular log shows that plymouth could not find any graphical
output to connect to, which is unusual.

[./plugin.c]                                create_backend:creating renderer backend for device /dev/dri/card0

[ply-renderer.c]                             ply_renderer_open:could not query rendering device for plugin /lib/plymouth/renderers/frame-buffer.so

What's unusual here is that FB_VISUAL_TRUECOLOR is exactly the one we
want.

Can you install the fbset package, and try running the following
command:

  sudo fbset -i

I also see in your dmesg output that this is a system that boots with
EFI.  So it's possible there's a race condition here in the handoff
between the EFI framebuffer and the nouveau framebuffer, that causes
plymouth-splash to try to start too early.

Title:
  [nouveaufb, efifb] blank screen on startup, "Visual is
  FB_VISUAL_TRUECOLOR; not using graphics"

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  This boot screen with "Ubuntu" and the dots works fine on the live CD. But after installation it is either a blank  black screen (mostly) or occasionally a purple screen with "ubuntu" in a tiny terminal type character font.
  On shutdown it usually shows purple screen with a tiny white ubuntu and some console type message across the screen.
  Logout briefly shows a black screen with tiny ubuntu text.

  This is on a Dell E521 with an nVidia Geforce 7300 LE card using the nouveau driver. 32 bit PAE kernel.
