If you install your Linux box with English as the primary language, you will notice the Chinese fonts are blurred and hard to read. That is due to anti-aliasing of Chinese characters. I would NOT recommend to disable all font anti-aliasing in Font Preferences, because anti-alias is good and it makes many fonts look easier for eyes, just not Chinese characters when they are small.

The solution is so set false for Chinese fonts under a specific font size. Create a file called local.conf under /etc/fonts/ directory

vi /etc/fonts/local.conf

and copy and paste the following to the file:

<?xml version=”1.0″?><!DOCTYPE fontconfig SYSTEM “fonts.dtd”>

<fontconfig>

<!– Disable font alias for Chinese <= 18px –>
