The job currently does: start on (... or (runlevel [016] and (stopped gdm or stopped kdm or stopped $otherdm))) However, if more than one of these dm packages is installed, at least one of these 'stopped $dm' events will be emitted *on system startup* because whichever DM is not the default will have its job started and immediately stopped. This means the second half of the AND is already satisfied, so as soon as the 'runlevel' event fires, plymouth starts up, racing the shutdown of the actually-running DM. And starting plymouth is bound to be faster than shutting down a running X session, which means plymouth and X are running at the same time and arguing about who controls the VT. The result is that plymouth starts rendering, then X sets the VT into text mode on shutdown, causing plymouth's progress indicator (5 cycling dots) to be drawn over the text screen. To fix this, we need the plymouth job to be able to distinguish between the *cause* of the DM job stopping. This probably means emitting a new event from the DM jobs, having plymouth look for this new event, and coordinating the transition with bidirectional Breaks: on the packages.
