CentOS 7w/Gnome在安装Nvidia驱动程序后挂在引导上？

Question

关于这些主题有很多可用的信息，但我还没有找到一个答案，我觉得这是一个非常普遍的情况。

我在一个带有CentOS 7和Gnome桌面的服务器上有2个Nvidia GTX 1080。GPU将专门用于CUDA的计算，而不是视频输出。

参见内核加载屏幕的屏幕截图。

我的xorg.conf看起来是这样的：

Answer 1

结果发现，Nvidia驱动程序安装程序破坏了一些涉及libglx.so的文件。我不知道确切的文件是什么，并且复制原来的libglx.so，在那里的一个Nvidia坚持，也没有带回东西。

使用"--no-opengl-files“安装标志，并在安装过程中提示覆盖xconfig时选择"No”解决了这个问题。

更详细的步骤是：

• 用Gnome桌面安装CentOS 7
• 启动后：
  • 百胜-y更新
  • 百胜-y安装内核-开发epel-发行版
  • 百胜-y安装dkms gcc gcc-g++
  • 重新启动(以获得新内核)

• 启动后：
  • sh latest_nvidia_driver.run -非opengl-文件
  • 当提示xconfig覆盖时，选择"no“
  • 设置默认的graphical.target (如果您的默认运行级别不是图形化的)
  • 重新启动
