（液晶显示器）我的arch linux字体采用DejaVu ＋微软雅黑，默认状态下，DejaVu的英文显示非常完美，笔画细腻清晰，但是雅黑就不怎么好，脏兮兮的而且不够锐利。但是开了整体hinting和次像素渲染后却影响了DejaVu。
解决方法：在/etc/fonts/local.conf（无则创建）添加以下内容，只针对雅黑打开hinting和次像素：
    <!--Hinting for Microsoft Yahei-->
    <match target="font">
  <test name="family">
      <string>Microsoft Yahei</string>
  </test>
  <edit name="autohint" mode="assign" >
          <bool>false</bool>
          </edit>
        <edit name="hinting" mode="assign" >
              <bool>true</bool>
        </edit>
        <edit name="hintstyle" mode="assign" >
              <const>hintfull</const>
        </edit>
  <edit name="rgba" mode="assign">
      <const>rgb</const>
  </edit>
    </match>


效果如图.


附上我完整的/etc/fonts/local.conf
