Les modules nvidia manquent après chaque mise à jour du noyau dans la version 18.04

Après chaque mise à jour du noyau, lorsque je redémarre, je n'obtiens qu'un écran vide.

Il semble que les modules propriétaires du noyau nvidia ne soient pas recompilés automatiquement.

Je dois démarrer en mode de récupération et faire

dpkg-reconfigure nvidia-dkms-415

et ensuite tout va bien jusqu'à la prochaine mise à jour.

J'ai essayé d'installer le pilote nvidia de nvidia, mais j'ai fini par l'enlever et utiliser celui d'ubuntu.

Je n'ai pas envie de réinstaller mon système.

sudo dkms status :
