Xubuntu 16.04 - optirun bumblebee 错误 [错误]无法访问辅助 GPU - 错误：[XORG]（EE）

Question

因此，在我开始或您提出重复问题之前，这里没有这样的事情xserver-xorg-legacy。我试过了这解决方案在这里，发现它不存在于我的驱动程序版本中。有一个类似的软件包，xserver-xorg-legacy-hwe-16.04但删除它会将驱动程序恢复到版本 304，在启动时安装 Bumblebee 会破坏整个笔记本电脑 - 我必须这样做apt remove。我曾尝试使用apt-mark来阻止它们自动卸载，但系统检测到它是不可能的情况。

无论如何，继续。我正在运行 Nvidia GeForce GTX 950M，并使用 Nvidia 驱动程序版本 384。但是，当我尝试测试时，它返回以下内容：

[错误]无法访问辅助 GPU - 错误：[XORG]（EE）

这是错误：

primusrun也返回相同的错误。我不知道是什么导致了这个错误，因为它似乎没有显示错误。

这是我的bumblebee.conf：

在此之前，我遇到了另一个错误，它显示。不过，我设法通过编辑bumblebee 配置中的所有内容[ERROR]Cannot access secondary GPU, secondary X is not active.来修复它。这里不再存在。nvidia-currentnvidia-384nvidia-current

这是我的xorg.conf.nvidia样子：

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"

尝试使用较旧的驱动程序，我遇到了 384 的问题，我不记得具体是什么问题，但是 375 和 378 现在对我来说运行良好。
