J'ai essayé depuis un certain temps maintenant de réduire mon temps de démarrage, en désactivant certains éléments de démarrage, en supprimant les paquets qui provoquaient des plantages après le démarrage, en supprimant les fichiers du pack ureadahead, en réinstallant ureadahead, en désinstallant ureadahead et en installant e4rat.... et rien n'a fait une grande différence. e4rat a fait la plus grande différence avec une réduction de quelques secondes mais mon temps de démarrage est toujours d'environ 80 secondes.
Quelqu'un peut-il m'aider ?
