接 usb3.0 HD，安裝 Linux
先試 ubuntu 18.04 (因為也是 LTS)。
用迴紋針按一下左邊側面的小洞，開機進入 bios。disable security boot。
用拇指疊開機，install 到另一個 usb hd
安裝一個 ESP partition 和一個 ext4。
開機按 F12 進入 boot 選單，會自動列出有開機能力的 partition (device)。
裝完也可以正常開機，但是 lspci 找不到 nvidia。
還有開一陣子system hang.. touch/keyboard 沒反應。
拆開，換上 8G ram 了。
猜開有點難，用指甲一點一點化開，但是 RJ45 那邊很緊，只好從後面開過來。
DDR 用一個鐵蓋子蓋起來。
follow 這一篇，他說 18.04 已經內建 cuda toolkit。所以用 apt 安裝就可以..
sudo apt install nvidia-cuda-toolkit sudo apt-add-repository ppa:graphics-drivers/ppa sudo apt update sudo apt install nvidia-driver-396重新開機。用 command 看..
