... as soon as you see the boot animation.  When you see the grey

you will typically see text that describes why the boot process isn't 
completing.

Because long ago the debugging text was deemed confusing, and a 
graphical wallpaper was placed over it.

That's unlikely.  Those packages are probably just hiding the actual 
problem.
