[Bug 1871717] Re: spinner theme, sometimes does not render splash without output

[Daniel van Vugt]

Yes plymouth is racey by design, which may be part of the problem. That
race involves waiting for 8 seconds for kernel DRM devices to appear and
if they don't appear in that time then they won't be used. Even if other
more basic kernel graphics devices do exist (like that used by the
BIOS). That issue is most recently being discussed in:
https://gitlab.freedesktop.org/plymouth/plymouth/-/issues/103 although
the underlying problem is not Nvidia-specific.

But it's unclear to me if that's the original problem here so I would
still wait for Dimitri to answer comment #6.

Title:
  spinner theme, sometimes does not render splash without output

Status in plymouth package in Ubuntu:
  Incomplete

Bug description:
  spinner theme, sometimes does not render splash without output

  desktop installer initrd starts plymouthd, executes show-splash, then
  casper md5check starts.

  Sometimes the progress bar and splash are shown with all the messages.

  Sometimes the screen remains black, but upon pressing ESC, one can see
  plymouth-text messages. pressing ESC again, rerenders the splash with
  casper-md5check progress bar with progress message, and file under
  check message, but not the Ctrl+C message.

  So plymouthd is there, and accepting input, but choosing not to paint
  things?

  From the 20200408 image.

  It is as if plymouth theme has a delay built in, and despite show
  splash.... it is not shown.

  When booting with plymouth:debug set, splash is rendered straight
  away.
