X11 fonts

[Patrick Useldinger]

Hi all,
a newbie question: I have just installed X11 (Xfree86 4.3), KDE (3.2.2) 
and Firebird (0.8), and surfing works very well. Compared to my Windows 
machine however, I think that the fonts look less appealing to what I am 
used to.
So I need a pointer - is this due to
1) the video driver? the card is an ATI Radeon 7500, and I configured 
the driver 'radeon' which should be correct.
2) the X11 fonts? which one 'look best'?
3) KDE - how can I make it to use the nicer fonts?
4) Firebird?
Regards,
