Si la pantalla de mi Retina MacBook Pro 2012 está inactiva cuando la computadora cambia de la tarjeta gráfica Nvidia discreta a la Intel integrada, WindowServer se congelará. Soy capaz de mover el cursor e incluso controlar las aplicaciones (por ejemplo, no pausar iTunes) haciendo clic a ciegas, pero la imagen en la pantalla no se actualiza.
Una forma segura de reproducirlo es conectarlo a la computadora a través de VNC, ya que la computadora cambiará a los gráficos discretos. Luego cierro el cliente VNC en mi teléfono y uso una esquina caliente para poner la pantalla en modo de suspensión. Cada vez que el servidor VNC se da cuenta de que el cliente está desconectado, vuelve a los gráficos integrados, lo que desencadena el error. Sin embargo, esto no es exclusivo de VNC, ya que puedo desencadenar este error con cualquier aplicación que use gráficos discretos.

Puntos de interés: 13:18:53, me conecto a través de VNC. 13:19:14, la computadora intenta cambiar a los gráficos de Intel y recibe muchos errores. 13:19:38, mato loginscreen a través de SSH para que WindowsServer se reinicie.
Esta es una instalación limpia 10.9.2 hecha ayer usando la partición de recuperación. El día anterior tuve una instalación 10.9 que actualicé de 10.8 y 10.7 que no tenía este problema, así que no creo que sea un problema de hardware. No tengo instaladas extensiones de kernel de terceros.
