Bonjour,
J'ai installé ubuntu 20.04 KDE Plasma sur un Macbook 13 pouces Aluminium de juin 2009 avec ubuntu comme system unique.
(J'ai fait cela afin de pouvoir utiliser un logiciel libre non maintenu sur Mac )
Cela fonctionne très bien le seul problème est le temps de boot que je trouve très long et un peu étrange.
Il se déroule ainsi
Timing du boot:
- 0s bruit que fait le mac au boot puis écran blanc
- 15s écran noir avec le caractère _ approximativement ligne 5 col
- 50s le caractère _ disparait. L'écran reste noir
- 1min 20s Un écran NVIDIA apparait
- 1min 40s L'écran de connection ubuntu apparait enfin
J'ai fait un boot info que voici
boot-info-4ppa125 [20210227_1107]

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda2,
using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.2 LTS CurrentSession entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !
J'ai fait le boot repair suggéré: En revanche je ne n'ai pas trouvé comment faire la derniere remarque: " Ne pas oublier de ..."

Résultat : Le boot n'a pas changé.
J'ai beaucoup cherché sur le forum mais je n'ai pas réussi à trouver une solution. ( finalement ce boot est peut être normal)
En revanche je ne comprends pas tout à fait les subtilités entre UEFI et GRUB ( j'ai peut être raté quelque chose à l'install).
Si vous avez une aide à me proposer je vous en serai très reconnaissant.
Merci
