http://forums.opensuse.org – Hi, I just installed openSUSE 11.3 (Gnome). I am using Korean language, but I don't want to make Korean language as my default language. So I installed Korean lang as secondary language. It works well. But the problem is Korean font. Actually BEFORE installing the language, the font look much nicer. But as soon as I installed the language, the font became ugly. Even if I uninstal the language, the font still remains the same (ugly). Where is the font setting for other languages stored? It would be nice if I can set default fonts for Korean la (Distributions)
