Bonjour
merci pour la réponse, oui depuis le tout début (appui sur on) donc affichage logo compris et grub compris.
Pour les commandes, je ne suis plus devant l'ordinateur là tout de suite, mais j'avais sauvegardé ceci qui y répond en partie :
fnelr@FNELR-OptiPlex-790:~$ systemd-analyze blame| head -6
31.406s blueman-mechanism.service
21.630s dev-sda1.device
19.465s udisks2.service
17.881s networkd-dispatcher.service
17.294s accounts-daemon.service
13.576s NetworkManager.service
et ceci
