私は専用のnVidia Geforce 940MX GPUを搭載したラップトップを持っています。https://wiki.ubuntu.com/バンブルビーしかし、実行しようとすると、optirun glxgearsメッセージが表示されて失敗します
[ 663.222353] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[ 663.222380] [ERROR]Aborting because fallback start is disabled.
/etc/bumblebee/xorg.conf.nvidia正しい BusID を入力するように指示されている指示に従おうとしましたが、xorg.conf.nvidia ファイルで指定されているのと同じ BusID であるlspci | egrep 'VGA|3D'次の出力が表示されます
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02) 01:00.0 3D controller: NVIDIA Corporation Device 179c (rev a2)
。この問題を解決する方法がわかりません。manjaro linux では、専用ドライバーで問題なく動作しましたが、Ubuntu では動作しないようです。
興味のある方のために、私の xorg.conf.nvidia ファイルをここに示します。

# If the X server does not automatically detect your VGA device,
# you can manually set it here.
# 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
# instance spawned to try to control the integrated graphics card,
# 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).
# If this option is not set, the new Xorg may blacken the screen and
# render it unusable (unless you have some way to run killall Xorg).
