这样是装好了么？而且为什么识别的是3DController而不是VGA　
系统运行起来稍微动动画面移动一下窗口 cpu占用率就飞升

因为optimus的设计，N卡没有连接显示器，而是连接到intel的核心显卡上了，提问之前请认真搜索

还有，新人发帖需要经过审核，在通过前请耐心等待，不要大量重复发内容相似的帖子（反正你发了也是在审核队列里面，别人看不到，只有自己干着急）

未看到 kernel driver in use: nvidia 字样，显卡未驱动。
GM108M [GeForce 940MX]，361.18 添加支持，请确保安装的私有驱动版本号大于等于 361.18。

版本367的专有NVIDIA驱动程序支持GeForce 940MX，它是在标准的Ubuntu 14.04/16.04/16.10软件存储库中提供的软件包nvidia-367。建议您使用标准Ubuntu 14.04/16.04/16.10软件存储库中的nvidia-367软件包替换当前安装的任何nvidia驱动程序。
