带有自定义 NVIDIA 驱动程序的 Ubuntu 16.04 登录循环

Question

我无法摆脱登录循环

1. 安装了 NVIDIA 驱动程序 367 的 Ubuntu 16.04

2. 禁用安全启动（我处于传统模式）

3. 显示管理器：lightdm

4. .xsession-errors：

openConnection: connect: No such file or directory
cannot connect to brltty at :0
upstart: gnome-session (Unity) main process (5813) terminated with status 1
upstart: unity-settings-daemon main process (5806) killed by TERM signal

upstart: indicator-session main process (5860) killed by TERM signal
upstart: indicator-application main process (5886) killed by TERM signal
upstart: unity7 main process (5843) killed by ABRT signal

互联网上的任何方法似乎都没有帮助。它让我疯狂。需要帮忙。

发生这种情况的真正原因是：我安装了 NVIDIA 自定义驱动程序，它在下面编译内核模块，并且一切正常。

由于是全新安装，Ubuntu 决定下载一些更新，并在升级过程中更新内核，并且可能会依赖其他一些编译 NVIDIA 驱动程序的库，这破坏了它们的二进制兼容性。

重新启动后，我陷入了 lightdm 的登录循环，并且无法使用 startx 运行我的 X 会话。看起来升级不仅破坏了与 NVIDIA 硬件加速渲染模块的兼容性，而且还破坏了软件模块，因此 Unity/Gnome 根本没有任何可渲染的内容。

为了解决这个问题，我只运行了我再次下载的 NVIDIA 安装脚本，重新编译后一切恢复正常。希望能帮助某人。

PS 我想指出的是，在我的解决方案中，返回蹩脚的显卡驱动程序是不必要的。
