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

У меня проблемы с ноутбуком Acer R11 (клиент). Он загружает Lan, получая образ своего диска с 14.04 LTSP Server. После первоначальной последовательности Acer Splash-DHCP-TFTP в скором времени появляется консоль, а затем Acer Splash (возможно, все еще в видеопамяти), а затем экран становится черным с 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 отлично работает (с сенсорным экраном), а LTSP 12.04 также работает (но без сенсорного экрана).

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

Я могу связаться с клиентом по ssh.

Я могу даже startx по ssh, а затем запустить xterm на server.

Когда я пытаюсь получить рабочий файл xorg.conf с Xorg -configure, я получаю ошибку: Number of created screens does not match number of detected devices.
