Bonjour,
Quand je branche un écran secondaire (que ce soit via DisplayPort ou VGA), l’écran principal :
- est toujours détecté (il apparait bien dans
Settings > Displays) - devient noir.
Et même si je débranche l’écran secondaire (qui lui fonctionne très bien), le premier reste noir et je dois redémarrer ma machine pour le faire fonctionner à nouveau.
J’ai essayé de supprimer ~/.config/monitors.xml mais ça n’a servi à rien.
Comment résoudre ce problème ?
Merci d’avance !
