Jetpack のインストール†

2016年10月26日時点での最新版はJetpack 2.3
- CUDA 8.0 の正式リリース版が含まれる
インストールには実機のLinux(Ubuntu)が必要

気長に待つ
途中、OpenCV4Tegraのインストールにこけた、とWarningが出た（何で？）
どうぜOpenCVはビルドするので、無視して先にすすめる
Network構成を言われるが、多分ここはUSBで直接繋いでいるから必要ないはず。適当に同じルータにぶら下がっていると説明しておいた。

gnome-tweak-toolを使う

$ sudo apt-get -y install gnome-tweak-tool
$ gnome-tweak-tool &

これで出てきた画面のうち Typing -> Ctrl key position -> Caps Lock as Ctrl を選択

SDカードを追加†

OpenCVビルド用の容量が足りなかったので、SDカードを挿して、GUIからext4にフォーマット
/media/以下のディレクトリを ~/opencvからシンボリックリンクを張って作業容量にした
