公司開發需要測試新的 AMD顯示卡，由於測試伺服器上的顯示卡是英偉達的顯示卡所以換完後要安裝相應的驅動。由於之前裝機的同事裝的ubuntu是18.04.5 恰巧18.04.5在amd官網上沒有相匹配的驅動（這裡由於開發之前在測試機上部署好了環境 就沒有及時將系統降級 耽誤了好久）
檢視版本： lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.5 LTS
Release: 18.04
Codename: bionic
可能是版本不一致導致的中間的一些包裝不了 換了個系統後再找相應的驅動包：https://www.amd.com/en/support/graphics/amd-radeon-5700-series/amd-radeon-rx-5700-series/amd-radeon-rx-5700-xt這是我的對應驅動包
安裝：
我用的是 os x就用他的命令列scp過去後
解壓
$ cd ~/Downloads $ tar -Jxvf amdgpu-pro-YY.XX-NNNNNN.tar.xz $ cd ~/Downloads/amdgpu-pro-YY.XX-NNNNNN
他裡面會有amdgpu-install 的自動安裝程式
執行./amdgpu-install 後觀察安裝過程有無報錯
這樣就差不多了 然後檢視
出現紅框內的引數就說明安裝成功了

glxinfo | grep rendering（）
如果結果是“yes”，證明顯示卡驅動已經成功安裝。
如果提示有問題，可能是系統裡面沒有安裝mesa-utils，安裝過程：在終端輸入命令：sudo apt-get install mesa-utils
然後再執行命令：glxinfo | grep rendering
這就差不多了結束了 ，安裝不成功首先要檢查系統版本跟驅動版本的問題 要保持一致。
總結：
- 下載對應讀驅動包
- 解壓安裝
- reboot（重點）
- lshw -C display
按照amd官網給的安裝過程較好
