Никакие устройства не нашли при попытке использовать NVIDIA GPU

Я пытаюсь использовать Шмеля для своего GPU NVIDIA, и я сталкиваюсь с ошибками при запущении программ.

Я тестирую его с клиентом Minecraft, который на самом деле запускается, но отказывает с момента.

$ primusrun java -jar Minecraft.jar
# some normal output...
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) No devices detected.

Я вижу карту очень хорошо:

$ lspci | grep 3D
01:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)

Эта установка хорошо работала при Arch на этой той же машине. Не уверенный, что не настроено правильно.

Править:

$ lspci -nnk | grep -iA2 VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06)
Subsystem: CLEVO/KAPOK Computer Device [1558:0650]
Kernel driver in use: i915

Моей основной видеокартой является Intel, так как это - машина Optimus.

#   If the X server does not automatically detect your VGA device,

#   To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
#   as you see in the commented example.
#   This Setting may be needed in some platforms with more than one
#   nvidia card, which may confuse the proprietary driver (e.g.,
#   trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
    BusID "PCI:01:00.0"

#   Setting ProbeAllGpus to false prevents the new proprietary driver

#   which is already being managed outside bumblebee.
#   This option doesn't hurt and it is required on platforms running
#   more than one nvidia graphics card with the proprietary driver.
#   (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
