![Optirun 在装有 nvidia geforce 940MX 的 Ubuntu 17.10 上失败](https://linux22.com/image/899017/Optirun%20%E5%9C%A8%E8%A3%85%E6%9C%89%20nvidia%20geforce%20940MX%20%E7%9A%84%20Ubuntu%2017.10%20%E4%B8%8A%E5%A4%B1%E8%B4%A5.png)
我有一台配备专用 nVidia Geforce 940MX GPU 的笔记本电脑。我按照https://wiki.ubuntu.com/Bumblebee但每当我想运行optirun glxgears
它就会失败并显示消息
[ 663.222353] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[ 663.222380] [ERROR]Aborting because fallback start is disabled.
我尝试按照说明/etc/bumblebee/xorg.conf.nvidia
输入正确的 BusID,但给出lspci | egrep 'VGA|3D'
的输出
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02) 01:00.0 3D controller: NVIDIA Corporation Device 179c (rev a2)
与 xorg.conf.nvidia 文件中指定的 BusID 相同。我不知道如何解决这个问题。在 manjaro linux 中,它可以与专有驱动程序完美配合,但在 Ubuntu 中似乎不起作用。
如果有人感兴趣的话,这是我的 xorg.conf.nvidia 文件:
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddDevices" "false"
Option "AutoAddGPU" "false"
EndSection
Section "Device"
Identifier "DiscreteNvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
# 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).
Option "ProbeAllGpus" "false"
Option "NoLogo" "true"
Option "UseEDID" "false"
Option "UseDisplayDevice" "none"
