+> 鬼知道这有什么意义，但是在 tty 里用 monospace 和 cjk 字体真的很酷
+
+## 安装
+
+AUR - `kmscon`
+
+## 启用
+
+```sh
+sudo ln -s '/usr/lib/systemd/system/kmsconvt@.service' '/etc/systemd/system/autovt@.service'
+```
+
+以及保留 tty1 为 getty：
+
+```sh
+sudo systemctl enable getty@tty1.service
+```
+
+理由：
+
+- kmscon 中通过命令行启动图形 session 会遇到问题。
+- 通常 tty1 用于运行图形界面，不需要 kmscon 提供的各种特性。
+
+## 修改默认配置
+
+```sh
+sudo systemctl edit autovt@.service
+```
+
+然后添加以下内容：
+
+```ini
+[Service]
+ExecStart=
+ExecStart=/usr/bin/kmscon --vt=%I --seats=seat0 --no-switchvt
+```
+
+解释：
+
+- 默认的 `ExecStart` 携带的参数会覆盖所有配置文件中的对应项，需要先清空。
+- 保留默认参数 `--login` 前的部分，因为我看不出不这么做的理由。
+
+然后就可以在 `/etc/kmscon/kmscon.conf` 添加自定义的配置了。
+
+例如：
+
+```conf
+login=/bin/login -p -f kolkas
+font-name=MesloLGM Nerd Font Mono, Maple Mono NF CN
+font-size=14
+```
+
+其中：
+
+- `login=/bin/login -p -f kolkas` 指定自动登录用户。
+- `font-name` 和 `font-size` 用于设置字体和大小。
+
+### 关于自动登录的补充说明
+
+如果想让 kmscon 在自动登录的同时启动非登陆 shell (例如 fish)，可以将配置改为：
+
+```conf
+login=/usr/bin/su - kolkas -s /usr/local/bin/fish-login-wrapper
+```
+
+其中 `fish-login-wrapper` 内容为：
+
+```sh
+#!/bin/bash
+
+if [ -f /etc/profile ]; then
+    source /etc/profile
+fi
+
+if [ -f ~/.bash_profile ]; then
+    source ~/.bash_profile
+fi
+
+# 设置环境变量以供后续脚本检测
+export IS_KMSCON=1
+
+# 设定 fastfetch 的 logo 类型为 logo (config/shell/.config/fish/post.d/fetch.fish 会读取该变量)
+export fetch_logo_type=logo
+
+exec /usr/bin/fish
+```
+
+如果不需要读取 profile 文件而直接将 fish 作为登陆 shell，可以将配置改为：
+
+```conf
+login=/usr/bin/su - kolkas -s /usr/bin/fish --login
+```
+
+### 关于字体的补充说明
+
+- kmscon 上 2 字符宽的 nerd font 图标会被裁剪至 1 字符宽。可以使用带有 Mono 后缀的 Meslo 系字体作为首选字体，它的图标字符只有 1 字符宽。
+
+- [Archwiki - KMSCON](https://wiki.archlinux.org/title/KMSCON) 上提供了另一种更改字体的方法，即修改 fontconfig 配置，具体做法为在 monospace 字体族中前置添加字体。但这会影响所有使用 fontconfig 和 monospace 字体族的程序，个人认为并非首选。
+
+## 检测当前终端是否为 kmscon
+
+> 以下代码片段适用于 fish shell
+
+检测所有祖先进程中是否有 kmscon：
+
+```sh
+function is_kmscon
+    set -l pid %self
+    while test $pid -gt 1
+        set -l info (ps -o ppid=,comm= -p $pid | string trim)
+        set -l ppid (echo $info | awk '{print $1}')
+        set -l name (echo $info | awk '{print $2}')
+
+        if string match -q "kmscon" $name
+            return 0
+        end
+        set pid $ppid
+    end
+    return 1
+end
+
+if is_kmscon
+    # 在 kmscon 中
+end
+```
+
+或如果配置了 [环境变量](#关于自动登录的补充说明)：
+
+```sh
+if test -n "$IS_KMSCON"
+    # 在 kmscon 中
+end
+```
