i3 の設定
始めに
スペックがあまり潤沢ではない機材を使うため, 軽量な wm として i3 を使い始めた.
元々常にtmuxを全画面にして作業しているので, 「タイル型wmの恩恵を受けられるのか?」という疑問はあったのだが, 使ってみたら「綺麗」かつ「驚きの軽さ」ということで, すっかり気にいってしまった.
i3 と一緒に使っているもの
とりあえず現状では以下:
- ターミナル関連: urxvt と tmux → Terminal生活
- ファイルマネージャ: pcmanfm
- ブラウザ: firefox + vimium-ff
- ランチャ: rofi
他にも
- Compositor: compton
- ネットワーク: Network Manager
- 音: pulseaudio
といった所はそのまま, かな?
i3 の設定
設定ファイルは末尾に掲載している.
xdg-open と run-mailcap
いわゆる GNOME や KDE といった Desktop 環境ではないので,
たとえば xdg-open の挙動が変わります.
それ自体は問題無いのですが, 以下の様に
applications/*; xdg-open "%s"
image/*; xdg-open %s;
video/*; xdg-open %s;
~/.mailcap を xdg-open に丸投げしていて, さらに $DISPLAY (もしくは $WAYLAND_DISPLAY)が無い場合には,
xdg-open が run-mailcap を呼ぶ→ run-mailcap が xdg-open を呼び, といった
無限ループが発生します.
run-mailcapを抜けば良い, という話もありますが, これ=mime-support=パッケージで提供されているので, 抜くとpython が抜けて大変な目に会います
というわけで, 安直には xdg-open を修正すれば良いですね:

Rofi: ランチャ
Rofi は良い感じのランチャ.
