There are xfree 4.0.1 packages by the Debian X maintainer, but they are still experimental and not part of Debian "proper."
If you want to try them, add deb http://samosa.debian.org/~branden/ woody/i386/ to your sources.list. Do an "apt-get update && apt-get dist-upgrade" and you'll update yourself. However, these packages are not part of the distribution, and you shouldn't use them if you're afraid of Things That May Go Wrong. That said, I recently tried upgrading and the packages upgraded extremely smoothly. There was a slight hiccup with the config file, but one symlink and I haven't had a problem since. // joey tsai :: Rogelio E. Castillo Haro :: > Do you know how to upgrade to Xfree 4.0?
