Forgot to add, after you uncomment the subpixel stuff, just do a `make && sudo make install && make clean` from the `xenocara/lib/freetype` directory.
Also, repeat the same after each snapshot upgrade, as the X sets will overwrite it every time, naturally. Don't forget to keep it updated as well, with `cvs up`.
Hm no.. have never heard of Infinality and didn't see anything OpenBSD-specific.
I'd say if you're needing extensive font support, or do any really heavy graphics work, OpenBSD may not work well for you as a desktop. For me, the stock fonts on OpenBSD meet my needs.
