Ubuntu 15.10 : bug d'affichage et message « CRTC »

Bonjour,

Depuis la mise à jour, j'ai une fenêtre d'erreur qui apparaît à chaque ouverture de session. Mais l'affichage de cette fenêtre elle-même est boguée !

Voici la capture d'écran.

Le bug graphique est le même que celui que j'ai publié il y a quelques jours dans la discussion Ubuntu 15.10 : bug du bureau (nemo ?) et qui avait été résolu par la mise à jour de nemo. Sauf que là, ça ne le fait que sur la surface de la fenêtre du message, pas sur tout le bureau.

Tant que la fenêtre est présente, certains raccourcis claviers ne fonctionnent pas (Impr écran, Ctrl+Alt+T...), comme l'autre fois. Tout semble lié mais je ne comprends pas.

Si je tue le processus unity-settings-daemon, cette fenêtre mystère disparaît, mais aussi mon thème graphique personnalisé (barres de titres en gris clair plutôt que foncé...). Je peux aussi fermer la fenêtre proprement avec Alt+Espace, puis Fermer. Elle réagit immédiatement.

Avant de la fermer, j'ai pu récupérer le contenu texte de la fenêtre en cliquant dedans, puis Ctrl+A, puis Ctrl+C :

could not assign CRTCs to outputs:

Je sais que c'est lié à l'affichage, mais j'y pige que dalle. Comment faire disparaître ce message d'erreur ?
