hello bonjour à tous !
je ne sais pas trop dans quelle rubrique poster !!!!
dans divers posts on parle de temps de démarrage
voilà ma question :
qu'appelle-t-on temps de démarrage ?
EDIT : question annexe : et alors comment mesurer ce temps
mesurer avec l'aiguille des secondes de ma montre
1ère colonne : temps de référence
2ème colonne : différence avec le précédent
==========================================
00s : 00s : appui sur le bouton "power"
07s : 07s : apparition de grub
30s : 23s : apparition de user ( et validation dans la foulée)
42s : 12s : apparition du bureau
===========================================
la 1ère et les dernières lignes de dmseg à partir de 5s
