ubuntu 手贱安装 nvidia-current nvidia-settings 导致无法启动桌面

[bigpigeon]

有什么办法可以恢复吗？我的 ubuntu 版本是 16.04

.xsession-errors 的错误是

Xlib:  extension "GLX" missing on display ":0".
openConnection: connect: No such file or directory
cannot connect to brltty at :0

登录界面 ctrl+alt+f1 进命令行把这两个包删掉试试？

我通过使用 bumblebee-nvidia 弄好了，不过另一个显示器还是不亮

@jmc891205 试过删掉，但不行

http://unix.stackexchange.com/questions/254377/xlib-extension-glx-missing-with-an-nvidia-card-and-on-board-graphics 试一试？ 最好的安装方法应该是装 cuda 的离线 deb 包， 妥妥的没问题

[bigpigeon]

@sleeperqp 我用 bumblebee-nvidia 了，不过另一个显示器还是没显示
现在.xsession-errors 是
openConnection: connect: No such file or directory
cannot connect to brltty at :0

[bigpigeon]

如果用光盘启动的 ubuntu 就可以检测到 2 个显示器
不知道是哪里配错了，有什么简单的还原方法么
