加载模块“nvidia”失败(模块不存在，0)

Question

我有nvidia GM206 (GeForce GTX960)。我正在使用Linux (Ubuntu14.04)，最近我安装了蒸汽。当它抱怨没有直接呈现时，我按照蒸汽群落中的指令在/usr/lib/nvidia-387和/usr/lib/nvidia-387中编辑alt_ld.so.conf。重新启动后，X无法启动，在重新安装nvidia驱动程序之后，我只能使用640x480分辨率，并且显示器被识别为膝上型计算机(尽管我在桌面上)。

现在，我的Xorg.0.log包含：

cat /var/log/Xorg.0.log | grep nvidia
[    19.039] (==) Matched nvidia as autoconfigured driver 0
[    19.039] (==) Matched nvidia as autoconfigured driver 2
[    19.039] (II) LoadModule: "nvidia"
[    19.039] (WW) Warning, couldn't open module nvidia
[    19.039] (II) UnloadModule: "nvidia"
[    19.039] (II) Unloading nvidia
[    19.039] (EE) Failed to load module "nvidia" (module does not exist, 0)
[    19.069] (==) Matched nvidia as autoconfigured driver 0
[    19.069] (==) Matched nvidia as autoconfigured driver 2
[    19.069] (II) LoadModule: "nvidia"
[    19.070] (WW) Warning, couldn't open module nvidia
[    19.070] (II) UnloadModule: "nvidia"
[    19.070] (II) Unloading nvidia
[    19.070] (EE) Failed to load module "nvidia" (module does not exist, 0)

我如何才能找到为什么nvidia-387不能加载nvidia模块，即使它已经安装？

可能会迟到，但可能会对某人有所帮助。

在我的例子中，这发生在我试图将nvidia驱动程序升级到更高版本的时候。在重新启动之后，X.org没有启动，并且dmesg有以下内容：

[  919.938560] nvidia-nvlink: Nvlink Core is being initialized, major device number 239
[  919.939080] NVRM: The NVIDIA GeForce 9600 GT GPU installed in this system is
               NVRM:  supported through the NVIDIA 340.xx Legacy drivers. Please
               NVRM:  visit http://www.nvidia.com/object/unix.html for more
               NVRM:  information.  The 390.138 NVIDIA driver will ignore
               NVRM:  this GPU.  Continuing probe...
[  919.939086] NVRM: No NVIDIA graphics adapter found!

因此，我收回了这一变化：

apt remove nvidia-driver-390; apt autoremove  # or whatever you tried to install
apt install nvidia-340
