Newbie question about X fonts

[Tran Tuan Anh <trantuan@comp.nus.edu.sg>]

Hi all:

I notice the font redering in Mozilla is not as good as in IE.
I remembered one of my friend told me that was because in Linux
we don't have some font technologies.
Is it still true now? or just because I don't config fonts setting
properly?

THanks!
