NVIDIA GPUにBumblebeeを使用しようとしていますが、プログラムの実行中にエラーが発生します。
Minecraftクライアントでテストしていますが、実際には起動しますが、しばらくするとクラッシュします。
$ primusrun Java -jar Minecraft.jar
# some normal output...
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) No devices detected.
私はカードをうまく見ることができます:
$ lspci | grep 3D
01:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)
このセットアップは、この同じマシンのArchで正常に実行されました。何が適切に設定されていないかわからない。

$ 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
これはオプティマスマシンであるため、メインのグラフィックカードはIntelです。

# 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.

# Setting ProbeAllGpus to false prevents the new proprietary driver

[ERROR] Cannot access secondary GPU - error: [XORG] (EE) No devices detected.
/etc/bumblebee/xorg.conf.nvidia
(またはnoveauドライバーを使用している場合は/etc/bumblebee/xorg.conf.nouveau
)を編集し、その中の指示に従って正しいBusIDを指定する必要があります。
たとえば、xorg.conf
は次のようになります。
Section "Device"
Identifier "DiscreteNvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce XXXXX"
BusID "PCI:2:0:0"
EndSection
XXXX
を見つけて、正確なBoardName
とBusID
をコマンドで置き換えます。
Sudo nvidia-xconfig --query-gpu-info
この再起動後、Sudo service lightdm restart
または再起動が機能します。
/etc/bumblebee/xorg.conf.nvidia
で、コメント解除します
BusID "PCI:01:00:0"
そしてそれを
BusID "PCI:0x:00.0"
ここで、xは「3Dコントローラー」の隣のlspci
リストに表示される番号で、nvidiaカードである必要があります
