统一登录环w/ nvidia gtx 1070

Question

昨晚我运行了一次升级，今天早上，在关闭之后，我正在经历一个登录循环(尽管我通常甚至没有显示登录屏幕)。我检查了..xsession错误，发现了以下内容：

openConnection: connect: No such file or directory
cannot connect to brltty at :0
upstart: gnome-session (Unity) main process (4070) terminated with status 1
upstart: unity-settings-daemon main process (4059) killed by TERM signal
upstart: logrotate main process (3887) killed by TERM signal
upstart: bamfdaemon main process (3973) killed by TERM signal
upstart: unity-panel-service main process (4077) killed by TERM signal
upstart: indicator-bluetooth main process (4110) killed by TERM signal
upstart: indicator-power main process (4111) killed by TERM signal
upstart: indicator-datetime main process (4113) killed by TERM signal
upstart: indicator-keyboard main process (4117) killed by TERM signal
upstart: indicator-sound main process (4118) killed by TERM signal
upstart: indicator-printers main process (4121) killed by TERM signal
upstart: indicator-session main process (4123) killed by TERM signal
upstart: Disconnected from notified D-Bus bus

我尝试过重新引导.Xauthority到备份文件，重新安装ubuntu桌面和ubuntu会话，以及chown .Xauthority。

我认为这是一个图形驱动程序的问题，因为当我出现在登录屏幕上，我的显示安排是不正确的(我有两个显示器)。

Answer 1

我自己想出来的。正如我所想的，nvidia司机才是问题所在。我查看了几个目录，仍然有nvidia 367.27图形驱动程序的.run文件。我删除了当前的驱动程序：

    sudo apt-get purge nvidia*

通过以下方式停止当前的Xsession：

    sudo service lightdm stop

最后，从我的下载文件夹中安装了驱动程序：

    sudo sh ~/Downloads/NVIDIA-Linux-*-367.27.run

运行sudo重新启动，一切都恢复正常。
