Это моя конфигурация экрана:
      +----------------+----------------+
      |                |                |
      |                |                |        This is X Screen 1
      |                |                |        Two 1680x1050 screens
      |                |                |
+-----+----------------+----------------+-----+
|                      |                      |
|                      |                      |
|                      |                      |  This is X Screen 0
|                      |                      |  Two 2560x1440 screens
|                      |                      |
|                      |                      |

Все работает хорошо, за исключением того, что когда я пытаюсь сделать полноэкранный режим или развернуть какое-либо окно, оно охватывает все два экрана любого экрана X, на котором он включен. Кроме того, диалоговые окна всегда делятся пополам по середине окна.
Я слышал, что metacity может не очень хорошо играть с Xinerama, но я не могу найти никаких официальных ошибок в интернете. Я думаю, что это также может быть моей конфигурацией, поэтому я решил опубликовать свою проблему здесь.
Вот мой xorg.conf:

Обратите внимание, как я сейчас создаю еще один экран X для каждого монитора.
