我将 TP W520 从 13.10 升级到 14.04，Optimus 13.10 下可以正常工作。设置如下：http://www.unixreich.com/blog/2013/linux-nvidia-optimus-on-thinkpad-w520w530-with-external-monitor-finally-solved/
升级之前，我删除了 xorg-edgers ppappa-purge
升级后我重申，我只能进入低图形模式。
我已经尝试再次添加 xorg-edgers 并清除/重新安装 bumblebee 和 nvidia，但没有成功。
我不知道出了什么问题……
更新：
当我打开控制台并使用：sudo pkill -9 Xorg然后：startx
我进入团结状态。

答案1
我注释掉了以下行/etc/lightdm/lightdm.conf
display-setup-script=/sbin/hybrid-power
现在我可以成功启动到 Unity
答案2
14.04 在混合显卡方面存在一些问题，特别是第二代英特尔处理器和带有 AMD/NVidia 独立 GPU 的高清显卡，
最好的解决方案就是使用开源驱动程序或从英特尔下载中心安装英特尔驱动程序， https://01.org/linuxgraphics/ 如果您不喜欢在 Linux 中玩高端游戏，请从这里安装驱动程序，这就足够了 :)
