No smooth transition out of X on shutdown

Bug Description

Binary package hint: plymouth

This isn't serious but annoying. If you use the shutdown function in X it closes and you see the console with all the usual text and error messages which looks like something has crashed. After one second or something like that Plymouth kicks in and shows the usual boot/shutdown screen.

Isn't it possible to let X directly change to Plymouth on shutdown (at least with KMS)? It would look much more coherent and professional.

As soon as this and Bug #535108 is fixed Ubuntu would look really coherent, professional and great and a normal user would never see "annoying" console messages. This is what the whole boot experience blueprint is about I think.

Sorry, we have to let the X server stop first before plymouth is started, so there's always going to be a gap here when we've dropped out to text mode on shutdown. I don't know any way to transition directly from X to plymouth on shutdown, and I think if Scott knew one it would already be implemented.

Thanks for the info. I just thought since the change from Plymouth to X is directly possible in Lucid the opposite would be too. Maybe Plymouth can run the whole time on one console or it is possible to change to a black screen from X but like I said it is not so important.
With installed cryptsetup/fixed Bug #535108 it just would look so great. :)

The difference is that plymouth is written to let other programs tell it that they're taking over the display and to exit leaving a splash screen up, but the X server is not. (Not to mention the extra layer of management, the display manager, that's in charge of the X server.)

Running Plymouth on a different console would not allow for a seamless transition; there would be a black screen of a VT switch between Plymouth and X - and the startup situation would be worse since X would not be able to inherit the screen contents.

As Steve says, in order to provide a smooth transition *out* of X, we need the X server to co-operate in the same way that Plymouth does on the way in

This may never happen; at least not before we change display servers and stop using X!
