1、下载字体：

sudo pacman -S xx # 安装字体
sudo fc-cache -fv # 刷新缓存
# 字体文件目录：/usr/share/fonts

adobe-source-sans-fonts # 思源Source Sans Pro英文字体
adobe-source-code-pro-fonts # Source Code Pro英文等宽字体
adobe-source-serif-fonts # 思源Source Serif Pro英文衬线字体
adobe-source-han-serif-cn-fonts # 思源宋体

2、设置系统字体，并将font dpi设为120或144

3、默认情况下，Fontconfig 的用户配置文件位于 ~/.config/fontconfig/fonts.conf

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'urn:fontconfig:fonts.dtd'>
<fontconfig>

   <!-- 关闭内嵌点阵字体 -->
  <match target="font">
    <edit name="embeddedbitmap" mode="assign">

 <!-- 字体微调的程度, 可选为 hintnone, hintslight (默认), hintmedium, hintfull. -->
  <!-- 简单来说，更高的 hinting 等级可以使字体更锐利，但同时也会损失更多的细节. -->
  <!-- 如果你的显示器的 DPI 高得不像话 (>=300), 那么就可以关闭 hinting, 因为字体会自然对齐像素. -->
  <match target="font">
    <edit mode="assign" name="hintstyle">
      <const>hintslight</const>

1. 打开/usr/share/fonts/目录
2. 创建truetype和opentype文件夹
3. .ttf扩展名的放在truetype 文件夹
   .otf 扩展名的放在opentype文件夹
4. 刷新缓存 sudo fc-cache -fv

sudo mkdir /usr/share/fonts/truetype
sudo mkdir /usr/share/fonts/opentype

sudo cp /path/to/fonts/*.ttf /usr/share/fonts/truetype
sudo cp /path/to/fonts/*.otf /usr/share/fonts/opentype

sudo fc-cache -fv
