Acer Aspire R3-131T R11 с LTSP 14.04 начинается с черного экрана

У меня проблемы с ноутбуком Acer R11 (клиент). Он загружается через Lan, получая образ диска с сервера LTSP 14.04. После начальной последовательности Acer Splash-DHCP-TFTP вскоре появится консоль, за которой следует Acer Splash (вероятно, все еще в видеопамяти), а затем экран становится черным с включенной подсветкой.

Установка LTSP 14.04 протестирована и работает с Asus Eee T101MT (включая сенсорный экран). Важно знать тот же Acer R11: Live USB 14.04 работает нормально (с сенсорным экраном), а LTSP 12.04 в качестве клиента также работает (но без сенсорного экрана).

Я отчаянно пытаюсь решить это. Я пробовал параметры ядра (nomodeset, noapic...)

Я могу связаться с клиентом через SSH.

Я могу даже запустить xx через ssh, а затем запустить xterm на сервере.

Когда я пытаюсь получить работающий xorg.conf с Xorg -configure ошибка, которую я получаю, Number of created screens does not match number of detected devices.
