Usually there's also a *.diff.gz.

Don't untar the gz -- you get the pristine upstream sources that way
without Debian/Ubuntu modifications and without a debian/ subdirectory
for building packages.

apt-get source untars the tarball and applies the Debian diff.gz for
you, so just cd xorg* and enjoy.

dpkg-source -x *.dsc is another way to unpack the Debian sources and
apply the Debian diff -- this is in fact how apt-get source does it
automaticall.

If you want to you can use bzr branch lp:ubuntu/karmic/xorg instead of
apt-source get.  If you want to make modifications, this can be more
convenient.  The downside is that you'll have to guess the source
package name, while apt-get source can convert a binary package name to
the right source package for you.
