我在我的 lenovo w520 上全新安装了 ubuntu gnome 16.04(没有格式化主分区;之前我使用的是 ubuntu gnome 15.10)。我的笔记本电脑(很遗憾 - 因为我一直遇到麻烦)上安装了 nvidia quadro 2000M(支持 optimus)。在 15.10 下一切正常。现在,当我安装 nvidia 专有驱动程序(nvidia-361)时,笔记本电脑屏幕无法检测到。如果我插入外接显示器,它可以正常工作,但笔记本电脑屏幕从不工作。有人有想法吗?我已经尝试重新配置 xorg,我删除了 ~/.config/monitors.xml 文件。还能是什么?可能是主目录中的旧安装中保留了一些配置?

看来是 361 驱动程序的问题。安装旧版本无法解决问题,但通过 ppa 安装 364 解决了问题。
