I'm not certain that this is strictly a matter for upstream developers
but I thought it worth reporting upstream just in case

I can only speak to my own experiences under Ubuntu 10.10 (x86-64)
wherein the visual transition between Plymouth and GDM is far from
smooth. Typically this visual transition entails an abrupt change to a
black screen between plymouth and GDM. I assume that this affects over
distributions and display managers.

If the following post to freedesktop's mailing lists
(http://lists.freedesktop.org/archives/plymouth/2009-June/000126.html)
is to be believed* this need not be the case. With a few patches to both
Plymouth and GDM they appear to have achieved a smooth transition of
sorts.

I'm not sure whether the Fedora developers approach is technically
desirable, but the current situation which entails a somewhat jarring
and abrupt transition to the display manager is sub-optimal in my
opinion.

Title:
  Transition between Plymouth and GDM is not smooth

Status in GDM: The Gnome Display Manager:
  Invalid
Status in The Plymouth splash screen:
  Won't Fix
Status in “plymouth” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: plymouth

  The transition between Plymouth and GDM is far from smooth, involving
  (in my experience) a brief black screen. This needn't be the case if
  this post
  (http://lists.freedesktop.org/archives/plymouth/2009-June/000126.html)
  regarding a smooth Plymouth➔GDM transition in Fedora is accurate.
  Details of how the Fedora developers allegedly* achieved this smooth
  transition are available via the above link.

  I don't know whether this is technically feasible, or even desirable,
  within Ubuntu. However that non-smooth Plymouth➔GDM is a blight on an
  otherwise splendid start-up process.
