Re: hypothèse

Pour en revenir à cette histoire de CRT dans les logs. Je suis remonté à de vieux log de Xorg.x.log et effectivement, c'est depuis récemment que j'ai cette suite de message :
Un grep EDID Xorg.0.log (du dernier boot donc) renvoie :

Alors que sur un plus vieux log :
grep EDID Xorg.2.log

J'ai l'impression que la carte graphique "croit" qu'un moniteur CRT est connecté. En faisant un grep Connected Xorg.* on voit clairement un Display1 qui apparaît…et pourtant aucun écran n'est branché…
