I've tried dugan's four packages(ubuntu and cleartype both), and the libXft patch from arch. Following is the snapshot of emacs after installing dugan's four packages and "mine":
If you look carefully, you'll find the fonts(minibuffer esp.) in dugan's is a little blurred. I've also tried dugan's libXft package with ubuntu patch, the same effects as above as far as I can see.
Dugans' other three packages work nicely here. So I prefer the combination of the cairo, freetype, fontconfig from dugan and libXft in the attachment.
