Ubuntu 16.04.5 LTS - [AMD/ATI] RS480 [Radeon Xpress 200 Series]

Bonjour,

Mon interface graphique ne se lance plus (peut-être suite à une mise à jour), après la connexion j'ai un fond d'écran et des messages d'erreurs en graphique disant qu'un problème est survenu, puis ce message disparaît.
Un ventilateur s'affole, et ça reste comme ça.
Le redémarrage avec la version précédente du noyau donne la même chose.
L'avant dernier noyau ne donne rien : busybox avec une console.
La création d'un nouveau compte utilisateur ne change rien.

La seule interface graphique qui fonctionne est gnome-flash-back.

Voici les infos :
