[Bug 810221] Re: Video output stops on real root after July 12 udev changes

[Luke]

As of July 16, this bug is only fixed when using Plymouth 0.8.4 , when
using Plymouth_0.8.2-2ubuntu24 the video output still cuts off.

With Plymouth 0.8.4, the text output is gone in such functions as
password prompting and the plymouth messaging. The video continues
during boot, but no text output. The password entry box still appears,
though-the problem is limited to text. I am using a custom plymouth
theme, but the text functions are cribbed from the ubuntu-logo script
and worked fine until initramfs-tools - 0.99ubuntu2. There was one
interesting behavior, though: When the video was cutting off, the font
for text changed to a heavier font when the video function came back on.

Text still renders fine with plymouth is run from X, as well it should
since plymouth has not changed. The older.

Plymouth_0.8.2-2ubuntu24, by comparison, still gave the video cutoff
when I tried it in an attempt to fix the text problem.


I have 0.8.4 installed as a legacy from the Natty round of Plymouth
message and password prompt problems, which the Ricotz PPA version
fixed.

Title:
  Video output stops on real root after July 12 udev changes

Status in “initramfs-tools” package in Ubuntu:
  Fix Released
Status in “initramfs-tools” source package in Oneiric:
  Fix Released

Bug description:
  In Ubuntu Oneiric, since the July 11/12 udev, initramfs-tools,
  basefiles (/var/run to /run ) changes, plymouth flickers to black,
  causing all video output to cut off ("no signal" report from monitors)
  until /etc/init/plymouth-upstart-bridge.conf runs, restarting video
  output.

  If /etc/init/plymouth-upstart-bridge.conf  is disabled as a test,
  video does not resume at all, showing this to be what is bringing it
  back.

  Booting with splash removed from the grub command line produces
  continuing video output without this flicker, though no script for
  logging output with plymouth produces output during this time (as my
  scripts normally would on console).

  Thus, it seems that either plymouth needs to be patched to adapt to
  the /run changes, or that there is a problem elsewhere concerning
  video devices during this transition.
