[环境搭建]ubuntu 16.04 安装

安装nvidia显卡驱动

网上的方法

https://blog.csdn.net/xunan003/article/details/81665835
其实应该有三种方法
ubuntu-drivers autoinstall 其中新的驱动上通过ppa的方式获得
sudo apt-get install nvidia-xxx
官方下载驱动安装

注意的事

一定要关闭bios的安全启动，上方链接有，具体表现为load xxmode failed

最后成功

我的笔记本是fx63vd,通过sudo apt-get install 和官网下载驱动安装，均可以成功，但是建议用sudo apt-get install 的方式，因为我的官网下载的驱动是没有nvidia-setting,nvidia-smi是都有可以看到的，打开nvidia-setting 切换集显和独显的时候会出些问题，比如切换完之后屏幕无法使用，导致重新装机。对此我毫无办法。

换源的问题

ubuntu需要换源速度才能加快，但是我遇到了一些问题，大家换源要去官网换源，比如我找的阿里源

大家可以看到稍微还是有些不同的，直接去阿里云开发网找源比较靠谱些，网上源之前也是一直这么换，但是这次我装机装软件的时候出现了依赖问题，总是出现xx依赖未被安装，后面我用了官方的源，装sougou输入法，装qt都很正常，当然也有可能是由于我一装完系统，换源之后，使用sudo apt-get update;sudp apt-get upgrade有关，至于怎么样，等下次电脑系统出问题再来研究，此处留坑。

笔记本显示屏不亮，只有外接显示屏亮

该问题，可能是由于显卡驱动造成的，我也是猜测，之前也是遇到过一次，我重装完成，这次我发现只要在启动界面，进入ubuntu高级选项，选择上一个内核版本即可，这个可能是因为nvidia的显卡安装对应了某个显卡吧
