Comment 19 for bug 585853

This appears to be caused by the xdm package not integrating with upstart. The plymouth process which holds the console open is waiting for a signal that the xdm job is starting up, so that it can let go of the console; but the xdm package, which is not well cared for in Ubuntu, doesn't have an upstart job, so there's no signal sent, which means the plymouth and xdm processes are fighting over the console.

Marking bug #723698 as a duplicate of this one. This is unfixed in natty, maverick and lucid.
