i3 wm

i3 윈도우 매니저는 C언어로 개발되었고, 비슷한 종류의 다른 타일링 윈도우 매니저들보다 비교적 최근에 나왔다는 특성이 있다. 때문에 부가적인 기능들이 대체로 잘 갖추어져 있고, 빠른 응답속도와 가벼운 크기를 잘 유지한다.

i3-gaps

최근에는 i3에서 포크하여, 윈도우간에 갭을 줄 수 있는 옵션을 추가한 i3-gaps가 오리지널보다 더 많이 사용되는 것 같다.

Rounded i3-gaps

여기서 한발 더 나아가, 윈도우 코너 부분에 라운드를 줘서 좀 더 예쁘게 수정한 Rounded i3-gaps도 있다.

여기서는 i3-gaps 또는 Rounded i3-gaps 어느쪽이든 소스코드를 clone 받은후, 컴파일해서 설치하고, 기본적인 설정을 부여해 주는 절차를 기술한다. 기본 OS는 Ubuntu 계열이면 다 된다.

전제조건

  • Ubuntu 계열일 것.
  • 디스플레이 매니저가 설치되어 있을 것. (gdm3, lightdm…)
  • git이 설치되어 있을 것.
  • 다음 유틸리티들도 설치되어 있으면 좋다 (설정파일과 그대로 매칭되는 권장사항) : qlipper, nm-applet, lxpolkit, pasystray, blueman-manager, feh, compton, terminator, min, firefox-trunk, pcmanfm, rofi …

빌드 및 설치 스크립트

3-gaps.sh 파일을 하나 만들고, 아래와 같은 내용을 써 준 다음 실행권한 부여하고 실행해 주면 된다.

#!/bin/bash
sudo apt install -y libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf libxcb-xrm0 libxcb-xrm-dev automake

mkdir $HOME/git
cd $HOME/git
 
# clone the repository
#git clone https://www.github.com/Airblader/i3 i3-gaps # Gaps
git clone https://github.com/resloved/i3.git i3-gaps # Gaps+Rounded
cd i3-gaps
 
# compile & install
autoreconf --force --install
rm -rf build/
mkdir -p build && cd build/
 
# Disabling sanitizers is important for release versions!
# The prefix and sysconfdir are, obviously, dependent on the distribution.
../configure --prefix=/usr --sysconfdir=/etc --disable-sanitizers
make
sudo make install
  • i3status 설치 : i3bar에 상태표시해 주는 앱을 추가해 준다.
sudo apt install i3status

설정파일

  • ~/.config/i3/config 파일을 만들고 아래와 같은 내용을 넣는다. (단축키 등 기본적인 설정은 거의 변경하지 않았고, 약간만 수정한 것임)
# This file has been auto-generated by i3-config-wizard(1).
# It will not be overwritten, so edit it as you like.
#
# Should you change your keyboard layout some time, delete
# this file and re-run i3-config-wizard(1).

# Font for window titles. Will also be used by the bar unless a different font
# is used in the bar {} block below.
#font pango:monospace 8
font pango:D2Coding 11
 
# This font is widely installed, provides lots of unicode glyphs, right-to-left
# text rendering and scalability on retina/hidpi displays (thanks to pango).
#font pango:DejaVu Sans Mono 8
 
# Before i3 v4.8, we used to recommend this one as the default:
# font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
# The font above is very space-efficient, that is, it looks good, sharp and
# clear in small sizes. However, its unicode glyph coverage is limited, the old
# X core fonts rendering does not support right-to-left and this being a bitmap
# font, it doesn’t scale on retina/hidpi displays.
