公司开发需要测试新的 AMD显卡，由于测试服务器上的显卡是英伟达的显卡所以换完后要安装相应的驱动。由于之前装机的同事装的ubuntu是18.04.5 恰巧18.04.5在amd官网上没有相匹配的驱动（这里由于开发之前在测试机上部署好了环境 就没有及时将系统降级 耽误了好久）
查看版本： lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.5 LTS
Release: 18.04
Codename: bionic
可能是版本不一致导致的中间的一些包装不了 换了个系统后再找相应的驱动包：https://www.amd.com/en/support/graphics/amd-radeon-5700-series/amd-radeon-rx-5700-series/amd-radeon-rx-5700-xt这是我的对应驱动包
安装：
我用的是 os x就用他的命令行scp过去后
解压
$ cd ~/Downloads
$ tar -Jxvf amdgpu-pro-YY.XX-NNNNNN.tar.xz
$ cd ~/Downloads/amdgpu-pro-YY.XX-NNNNNN
他里面会有amdgpu-install 的自动安装程序
执行./amdgpu-install 后观察安装过程有无报错
这样就差不多了 然后查看
出现红框内的参数就说明安装成功了

这就差不多了结束了 ，安装不成功首先要检查系统版本跟驱动版本的问题 要保持一致。
总结：
- 下载对应读驱动包
- 解压安装
- reboot（重点）
- lshw -C display
按照amd官网给的安装过程较好
