Bonsoir
@kalimeth : De ce que j'ai compris les fichiers bootia32.efi et grubia32.efi ont la meme fonction : permettre le lancement de grub sur un UEFI 32bit... Si tu as pu lancer le liveUSB sans grubia32 c'est qu'il n'était pas necessaire. Apparement il est possible de construire/compiler ces fichiers avec la commande
Vu ici.
grub2-mkimage
D'après moi grubia32 ne resoudra pas le probleme de son. Par contre si tu as une cle USB de disponible tu pourrais essayé d'autres distributions linux en LiveUsb pour voir si le son fonctionne, toujours en ajoutant le fichier bootia32 pour pouvoir booter...
L'installation de Lubuntu20.04 a été laborieuse mais finalement reussie : le son et le wifi fonctionnent toujours par contre pas de bluetooth (mais je préfère avoir le son, il n a jamais fonctionné sous 18.04 et j en ai pas besoin).
Le plantage lors du visionnage des video youtube a été résolu en creant un fichier d'echange SWAP de 1536mb avec la
methode décrite ici
Quelques problemes a resoudre plutot liés a la gestion de l'energie et à l'authentification mais je crois que ca avait été pareil au debut sous 18.04 (dommage que j ai pas pensé a sauvegarder le grub.conf)
Une autre distribution fait fonctionner le son et le wifi sur le minipc (par contre meme si un fichier bootia32.efi etait present sur le .ISO que j'ai téléchargé la liveUSB ne se lancait pas --> je l'ai supprimé et mis mes deux fichiers habituels a la place) :
