Comment from Shengyao Xue (xueshengyao):
I downloaded Trusty daily-live (20140224) and installed on ThinkPad
T440s.
And I found the Text seen during shutdown issue still can reproduce
sometimes.
the issue is same to video attached here:
https://bugs.launchpad.net/dell/+bug/1013355/comments/1
I tried trusty-desktop-amd64.iso (2014-02-24 daily build) on 2 Dell
platforms and can not reproduce this issue on them. One is a HSW
machine, and another is an AMD machine. Because both of them are not
RTSed yet, I can not leak too much information of them.

After extensive testing, i believe there is benefit in clearing tty in
plymouth pre-stop instead. And in some configurations post-stop can be
completely dropped if tty is cleared in pre-stop and no artificial 1s
delay which is very noticeable on SSDs. I'll test this a bit more, and
maybe upload

Ordering of the splash ahead of emitting rc runlevel level has been done
before in Fedora, to properly show shutdown splash to avoid scary
messages.
I have also noticed that there are additional messages generated on the
VT through the lifecycle of the machine - that is after lightdm cleared
it
So I've had a look at trying to start plymouth before lightdm has
shutdown, in order to start capturing console messages sooner.
Unfortunately this doesn't work right, lightdm shutting down puts the VT
into a state that lightdm isn't expecting so the splash doesn't update
the screen correctly.

Hi Steve,
I've linked a branch that clears the vt before lightdm starts up, so any
cruft that was echoed out to the terminal will not survive when lightdm
stops . This fixes the first bullet you mentioned, and also fixes this
problem when you do S3. I've taken the additional step of coloring the
For the record, this is also sort of similar to what chromeos does
today:

James, the vt definitely needs to be cleared after plymouth exits (i.e.,
after lightdm starts up), not before, in order to avoid races. Brian
Murray has been looking into this; Brian, any further progress?
As for the second bullet, basically the way to fix this is to make sure that
upstart
So there is a bug here with upstart, but I think it's more subtle than
what you describe. There's really no strict ordering of any of the jobs
at shutdown time, *except* that the plymouth splash screen is started
immediately after lightdm exits. Delaying the shutdown of all other
services
I messed around with this a little today, inspired by the news of the
new kernel vt-switchless resume support. You can definitely work around
this by doing:
printf \033[0;30m /dev/tty7
clear /dev/tty7
However, the real bug here is with upstart. It seems that upstart
chooses to execute a few of

This approach doesn't really work. Not only is clearing the text likely
to be visible, but other daemons which are in the process of shutting
down will still be printing stuff to the screen before plymouth comes

A bot changed to intel driver, but that's at least not correct. Changing
to plymouth, since I guess lightdm at least isn't running at the time of
logging out or shutting down (it's then started if it was logout in
question). Plymouth should have the splash screen available right away
when shutting
Yes, there seem to still be some races we haven't figured out yet where
plymouth will start up before lightdm has torn down the display,
resulting in the console being shown instead of the splash screen. (I
think there may be another bug already open about this, but I haven't
