Take Red Hat 7.3 as an example, when installing http://www.aliyun.com/zixun/aggregation/23115.html "> Simplified Chinese installation, first copy a SIMSUN.TTC to/usr/x11r6/lib/ X11/font/truetype, renamed Simsun.ttf; then enter/usr/x11r6/lib/x11/font/truetype directory, run ttmkfdir > Fonts.dir command; Edit the Fonts.dir file and modify the Simsun.ttf line as follows:
simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-c-0-ascii-0
Simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-c-0-iso10646-1
Simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-p-0-iso8859-15
Simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-p-0-iso8859-1
simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-c-0-gb2312.1980-0simsun.ttf-misc-simsunmedium-
r-normal--0-0-0-0-p-0-gb2312.1980-0
simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-m-0-gb2312.1980-0
simsun.ttf-misc-simsun-medium-r-normal--0-0-0-0-p-0-gbk-0
Then run the cat fonts.dir > Fonts.scale command, modify the/etc/x11/xf86config-4, and add the following line to the section "Files":
Fontpath "/usr/x11r6/lib/x11/fonts/truetype"
Finally back to the KDE desktop, in the "start" → "options" → "Impressions" → "font", change all fonts to SimSun
