Login Ubuntu 16.04更新时的登录循环

我通读了所有提出的解决方案和其他地方。他们都没有工作。以下是.xsession错误的外观：

openConnection: connect: No such file or directory
cannot connect to brltty at :0
upstart: gpg-agent pre-start process (2326) terminated with status 1
upstart: gnome-session (Unity) main process (2413) terminated with status 1
upstart: unity-settings-daemon main process (2398) killed by TERM signal
upstart: logrotate main process (2306) killed by TERM signal
upstart: update-notifier-crash (/var/crash/_usr_lib_x86_64-linux-gnu_indicator-application_indicator-upstart: application-service.1000.crash) main process (2354) killed by TERM signal 
upstart: bamfdaemon main process (2399) killed by TERM signal 
upstart: unity7 main process (2411) killed by TERM signal 
upstart: hud main process (2423) killed by TERM signal 
upstart: Disconnected from notified D-Bus bus
upstart: unity-panel-service main process (2421) killed by TERM signal 
upstart: window-stack-bridge main process (2332) killed by KILL signal

这个解决方案（有些，见下文）对我有效

按Ctrl+Alt+F3从图形登录屏幕进入tty终端

使用您常用的凭据登录

运行以下命令：

sudo获得净化nvidia-*

重新启动后，使用图形登录屏幕登录

我看到一个菜单通知我“Ubuntu正在运行非常低分辨率的图形”，并问我该怎么做。我选择了默认值。YMMV 我仍然在别处看到其他海报建议安装nuevo以获得高质量的图形。我还没有完成这部分

那些正在寻找这个问题的编程方面的人可以看到海报在哪里要求基于内核的解决方案

不是一个编程问题-试试看？
