Problème lors du passage de 14.04 à 16.04

Bonjour,
    Depuis une migration depuis Ubuntu 14.04, qui marchait convenablement sur ma machine, vers Ubuntu 16.04, je rencontre quelques problèmes. (J'avais déjà rencontré pas mal de souci lors de l'installation de la version 14.04, voici un topic contenant le problème d'alors: https://forum.ubuntu-fr.org/viewtopic.p … 93344&p=2)
En effet lorsque je choisis Ubuntu dans le grub, ma machine reste bloquée au bout de quelques secondes sur un écran violet, m'obligeant à éteindre la machine de force. L'alternative que j'ai trouvé pour pouvoir lancer Ubuntu est de choisir Options avancées d'Ubuntu => Ubuntu 4.2.0-42 generic.
    A partir de là, tout marche plutôt bien, mis à part les touches Fn qui ne marchent pas (modification du volume, de la luminosité, du touchpad).
J'aimerai donc savoir s'il y avait un moyen de régler ce problème et ainsi de ne pas avoir à m'embêter à choisir les options avancées à chaque démarrage.

Voici un boot-info fait à l'instant,
http://paste2.org/x1BpF10J


Merci d'avance! :-)

Bonjour
Merci d'avoir fourni l'ancienne discussion
Actuellement dans le boot-info on voit 

acpi_osi=

Tu devrais remplacer cette valeur par ce qui est indiqué ici

Re : Problème lors du passage de 14.04 à 16.04

Bonjour!
Je viens de rajouter nomodeset et acpi_osi=off dans /etc/default/grub, et en effet ça marche. Par contre je n'ai toujours pas accès aux raccourcis Fn (sauf ceux du volume). En plus Ubuntu est plus lent à lancer de cette façon, je crois que je vais rester sur la méthode Ubuntu 4.2.0-42 generic. Merci !

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda5 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 16.04.1 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


=================== User settings
The settings chosen by the user will not act on the boot.

Tu peux effectivement rester sur la "méthode Ubuntu 4.2.0-42 generic." mais il faut que tu sois conscient que ce noyau est obsolète et ne sera jamais mis à jour. Je te déconseille de rester dans cette position et t'encourage à continuer à chercher des solutions pour faire fonctionner Ubuntu 16.04 avec son noyau 4.4.0-x.
