La version de mon noyau est-elle correcte ou dois-je la mettre à jour?
J'utilise Ubuntu Precise:
$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS"
mais la version de mon noyau est:
$ uname -r
3.0.0-12-generic
Cette configuration est-elle correcte ou dois-je mettre à jour mon noyau avec une version plus récente? Si oui, comment puis-je le faire?

Vous avez l'ancienne bouffe. La mise à jour de grub résoudra le problème car le nouveau grub permet de mieux suivre les noyaux et autres systèmes d’exploitation sur les disques durs.
Suivez cette procédure pour: http://help.ubuntu.com/community/Grub2/Upgrading
Merci à ser68186
À ma connaissance, la dernière version disponible dans le référentiel est 3.2.0-31-generic. Cela signifie que votre noyau est en effet assez obsolète. La meilleure pratique est de toujours garder votre ordinateur le plus à jour possible et Ubuntu ne fait pas exception.
Vous pouvez mettre à jour le noyau sur un système de bureau en utilisant les commandes suivantes:
Sudo apt-get update
Sudo apt-get install linux-generic linux-headers-generic linux-image-generic
Si vous souhaitez également mettre à jour tous les autres logiciels, vous pouvez le faire en exécutant les commandes suivantes:
Sudo apt-get update
Sudo apt-get dist-upgrade
Soyez averti que ces commandes nécessitent les privilèges Sudo (admin) et que vous devez redémarrer par la suite.
Plus simple consiste à utiliser le gestionnaire de mise à jour pour rechercher les mises à jour et les installer:
Dans mon cas je devais mettre à niveau la pile d'activation matérielle HWE , afin de recevoir le dernier noyau.
