（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
