Bonjour,
J’ai installé Debian 7.8 en dualboot sur mon Imac 20" de mid 2010.
Ma carte graphique est la carte NVIDIA GE9400.
Souvent mon écran se fige partiellement voire complètement.
Le pointeur de ma souris peut continuer à bouger, mais n’interagit plus du tout avec le bureau.
Lorsque qu’il bloque complètement, il me faut donc faire un hard reboot pour relancer ma machine.
Je me demande si cela vient du pilote de ma carte graphique qui est mal installée?
Pour info:
