[Bug 1753467] Re: After clicking Try Ubuntu, Plymouth text appears

[Steve Langasek]

I don't think this text is "from" plymouth; I think it's from systemd.
TTBOMK we actually currently have no integration between systemd and
plymouth, such that systemd is writing its own messages to the console;
which happens to most of the time be hidden because the console is in
graphical mode so you only see the plymouth splash.

What's meant to happen is that we transition from the plymouth splash to
the display manager without ever putting the console back into text mode
(flicker-free boot).  So if we're seeing the plymouth messages, this is
failing somehow.  The original bug report was with the vboxdrmfb video
driver.  Brian, which video driver did you see this with?

(I'm not sure how the vboxdrmfb module was in use, since that is not
part of the main kernel package and should not be on the live image.)

I'm not sure whether we should also be configuring systemd to not
display these boot messages in the live image.

Title:
  After clicking Try Ubuntu, Plymouth text appears

Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  After clicking Try Ubuntu, text from Plymouth appears:
  [ OK ] Listening on Load/Save RF Kill Switch Status /dev/rfkill Watch.
  [ OK ] Reached target Sound Card.

  This isn't ideal behavior because Ubuntu should go straight from Try
  Ubuntu to the desktop session without dropping back to Plymouth text
