upgrade 16.04 freeze écran de connexion

Bonjour

Il y a maintenant quelques semaines, j'ai mis a jour vers la version 16.04 LTS d'ubuntu. Depuis, un problème majeur: une fois sur deux, au démarrage, a l'écran de connexion, le pc freeze totalement, juste après que l'écran soit apparu. Plus de souris ou clavier possible, que ce soit clavier et souris externe ou le pad et le clavier interne du pc (un portable): pas même moyen d'accéder a la console. J'ai essayé d'installer gdm et je l'ai mis a la place de ligthdm, même problème. C'est réellement une fois sur deux: après plusieurs dizaines de redémarrages, je peux confirmer de la constance de ce phénomène.
C'est assez problématique, surtout étant donné que mon pc démarre trèèès lentement (étrangement, il n'est pas spécialement lent...)

Merci de toute pistes d'aide !
(j'ai évidement cherché sur internet autant que possible, sur les sites anglais également... rien ne semble fonctionner….)
