Пытаюсь подключить к одному компьютеру две мыши/клавиатуры/монитора.

Вот мой конфиг xorg.conf:

Если раскоментировать "Screen 1 "Screen 2" LeftOf "Screen 1"", то оба монитора включаются, и второй является продолжением первого. Но если попытаться запустить только второй монитр (второй видеовыход - Seat2), то появляется сообщение об ошибке:
