Μερικές φορές έχω και γω το ίδιο πρόβλημα με Xubuntu 12.04.

Βάλε τα τελευταία updates (security και recommended) και δες αν αλλάζει 
κάτι. Προσπαθούν να διορθώσουν ένα race condition σε κάποιον logger κατά 
την εκκίνηση εδώ και καιρό. Πριν απο 1-2 βδομάδες νομίζω διόρθωσαν κάτι 
στον rsyslogd. Τώρα κάνουν λόγο για ένα fix που αφορά το plymouth.

Description-en: graphical boot animation and logger - main package
  Plymouth is an application that runs very early in the boot process
  (even before the root filesystem is mounted!) that provides a graphical
  boot animation while the boot process happens in the background.
