Anti-Aliasing

Hi SuSE 9.2 has really nicely anti-aliased type compared to Debian which I also have on my system - good solid lettering, good contrast between black and white, minimal smudging around letter forms, etc. I'm guessing that the SuSE technicians must have tweaked a few files to achieve this. Does anyone know which ones? I'd like to try to improve the rather basic look and feel on my Debian install. TIA :) Fish
