Xinerama с аппаратным ускорением одновременно

Есть ли какой-нибудь способ, которым я могу включить Xinerama и все еще использовать аппаратное ускорение? У меня три монитора на 2 графических процессорах. Я включил Xinerama, но теперь все аппаратное ускорение прошло. Это приводит к плохой частоте кадров в играх, и Compiz не работает должным образом. В случае, если это невозможно, есть ли способ перемещать приложения между экранами X без Xinerama? Вот мой xorg.conf, сгенерированный настройками NVIDIA X Server:
