Дешифровка ошибок Nvidia-375/var/log/syslog

Я надеюсь, могу ли я выяснить эти сообщения об ошибках Nvidia, я могу получить его работающий правильно:

Примечание: Я могу подтвердить вышеупомянутое сообщение об ошибке "Процесс, '/usr/bin/nvidia-smi' отказавший с кодом выхода 2", потому что я пытался выполнить его перед этим для наблюдения, какая информация могла мерцаться о GPU.

История

Я использовал prime-select nvidia включать Nvidia. Затем это загрузилось на черный экран входа в систему. Я обновил параметры ядра личинки с nomodeset:

• Внешний дисплей (HDMI 1920x1080) исчез
• Значки на рабочем столе, накопленные друг на друге у основания дисплея
• Ползунок регулировки яркости исчез

Примечание: Nvidia geforce GT650M раньше обнаруживался, но он исчез сегодня после возврата от Intel до Nvidia и назад к Intel.

Xorg detected your mouse at device /dev/input/mice.
Please check your config if the mouse is still not
operational, as by default Xorg tries to autodetect
the protocol.

Your xorg.conf file is /home/Me/xorg.conf.new

To test the server, run 'X -config /home/rick/xorg.conf.new'

(EE) Server terminated with error (2). Closing log file.

Сгенерированный файл конфигурации Xorg не имеет Nvidia разделами все же. Остановка lightdm сервис через консоль и выполнение конфигурации там также завершаются с ошибкой (2).
