I get a 640x480 logo on shutdown also.

This is the link for that fix. It is in #2 by Scott James Remnant.
I have found no problem with reduced boot speed.

The problem here is the graphics drivers; on your system they're taking longer to load than it takes to check and mount the filesystem - so there's no reason to start the splash screen, since we can already start X.

On HDD-based systems this is worse because we do the ureadahead phase before loading drivers; thus it can take a long time for a splash to appear.

One "solution" is to use the initramfs and start plymouth as a critical step:

  echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash
  update-initramfs -u

But that introduces a significant delay into boot just to get the splash screen up for the rest of it.

Must be in root when adding solution.

As for 640x480 can be changed in GUI package startupmanager.

Can you help with this problem?
