我有一台带有两个 GPU（Intel HD4600、Nvidia GTX850M）的笔记本电脑，它使用 GRUB 与 Windows 10 一起运行 Ubuntu（没有问题）。

我已经安装了nvidia-355，但由于不好的经历而没有安装bumblebee（从来没有让它工作/它或我破坏了安装）。

问题：

当我有繁重的图形负载时，与显示/图形相关的东西会崩溃，并且我看到启动消息的一部分短暂闪烁，然后我再次进入登录屏幕。

列出两个 GPU 的 lscpi 输出

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 850M] (rev a2)

dmesg 输出

[ 3266.232929] NVRM: GPU at PCI:0000:01:00: GPU-d1657723-9e43-04db-5cdc-6df0c522eb41

这样的动作被重复了一百次。

我这个周末搞砸了xorg.conf，以前看起来像这样：

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "intel"
    Driver "intel"
    BusID "PCI:0@0:2:0"
    Option "AccelMethod" "SNA"

EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

我尝试更改的任何内容都会在下次启动或图形登录时被覆盖。
我添加nogpumanager到我的启动选项并让 Nvidia X 服务器设置为我生成此配置：

    EndSubSection
EndSection

不知怎的，它在启动时没有被覆盖。

是什么导致我的体验不太顺利？我该如何解决？

图形驱动程序、驱动程序配置以及可能阻止我启动到 GUI 的东西都不是我的强项，因此我只愿意尝试在出现问题时可以恢复的东西。

我知道的：

  • 在没有该标志的情况下启动nogpumanager会将我的 xorg.conf 恢复为默认值。
  • 使用 nvidia 驱动程序而不是 nouveau 将阻止启动到 GUI。

编辑：

我尝试重现该问题，但发生了其他情况。打开几个程序后，图形用户界面在 alt-tab 上冻结并变成一片漆黑。程序中的任何声音都没有停止，而且我能够访问 TTY。我需要重新启动 lig​​htdm 才能返回 GUI。

~/.xsession-errors （完整输出，只有两行）：
