登录循环- ubuntu 16.04 - nvidia

Question

我尝试了几个问题中推荐的内容，这些问题涉及“登录循环”，但没有一个解决方案起作用。顺便说一下，我有一个nvidia GPU: GTX 1080。

另外，我也尝试过，但没有结果：

• 复制.Xauthority和.ICEauthority，或将所有权更改给用户。
• 拆卸和重新安装轻型设备
• 清除nvidia驱动程序：sudo apt-get remove --purge nvidia-*、sudo ubuntu-drivers autoinstall、sudo service lightdm restart和重新启动

按照这个问题建议，我包含了.C11的输出。

问题基本上是nvidia驱动程序把系统搞砸了，以至于nvidia重新安装没有像预期的那样工作。

他们说，要诊断这一点，必须运行终端:返回的nvidia-smi。NVIDIA SMI失败，因为它无法与NVIDIA驱动程序通信。

解决方案基本上是完全重新安装操作系统。所以在USB驱动器中下载ubuntu 16.04，重新安装ubuntu.

然后：

$ sudo apt-get install linux-headers-$(uname -r)
$ sudo apt-get --purge remove nvidia-*
$ sudo apt autoremove

这是GTX 1080的驱动程序，它来自：https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64和目标_distro=Ubuntu&target_version=1604&target_type=debnetwork

$ sudo dpkg -i cuda-repo-ubuntu1604_9.1.85-1_amd64.deb
$ sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
$ sudo apt-get update
$ sudo apt-get install cuda

然后重新启动，现在一切正常。谢谢nvidia你的垃圾软件！

由于您正在使用nVidia GTX卡，请尝试按Crtl + Alt + F2，登录，然后运行

数独-净化英伟达。*

然后重新启动。

如果您正在使用大黄蜂在GPU卡之间切换，则命令应该是

数独-净化nvidia。*大黄蜂。

编辑:我让nVidia在16.04使用nVidia驱动程序。我设法找到的唯一的驱动程序是nvidia-364，来自ubuntu图形ppa。以下是我所做的：

首先清除所有现有的nVidia驱动程序

数独apt-得到净化nvidia*

重新启动系统。

然后从存储库ubuntu图形ppa安装nvidia-364。

sudo add-apt存储库ppa:图形驱动程序/ppa sudo apt-获取更新sudo apt-获取安装nvidia-364

那就重新启动。

如果这不起作用，我也会尝试清洗库达。
