As the question, I am a Chinese user, the system version is linuxmint xfce 20.1. I want to use Ubuntu to display English and noto sans cjk sc to display Chinese. I looked at the config from archwiki and tossed it around a bit, but it didn't work. Here is the configuration in

Code: Select all

~/.config/fontconfig/fonts.conf

I don't know how to set it...

Code: Select all
