Опубликовано сравнение (http://www.phoronix.com/scan.php?page=article&item=387&num=1) двух технологий - Xinerama (http://sourceforge.net/projects/xinerama) и TwinView, позволяющих расширить одну активную десктоп среду на два монитора (один виртуальный дисплей).
TwinView реализуется закрытыми драйверами NVidia, а Xinerama - стандартное расширение XOrg. В статье рассказывает о настройке обоих режимов и приводятся результаты тестирования производительности.
