![大黄蜂重启后安全故障 x [GTX 755M]](https://linux22.com/image/1130499/%E5%A4%A7%E9%BB%84%E8%9C%82%E9%87%8D%E5%90%AF%E5%90%8E%E5%AE%89%E5%85%A8%E6%95%85%E9%9A%9C%20x%20%5BGTX%20755M%5D.png)
当我安装 bumblebee 和 nvidia-340 驱动程序时，Ubuntu 启动进入正常会话。下次重新启动时，在上一个会话中使用 optirun 运行 glmark2 后，正常的 x 会话无法启动，而是出现一个屏幕，显示“系统正在低图形模式下运行”消息。如果我使用以下命令将生成的 xorg.config 锁定为空白文件
$ chattr +i /etc/X11/xorg.config
我进入登录屏幕，但当我登录时，某些东西崩溃了，我再次返回到登录屏幕。
