Gnome first, before removing Xfce. Otherwise you will remove libraries
which you will later re-emerge for Gnome.
Then you need to configure your display manager (kdm, gdm, xdm) to use
Gnome instead of Xfce. Kdm and Gdm should allow you to do that directly
on the login screen.
When you are satisfied with Gnome, edit /var/lib/portage/world and
remove every line containing an Xfce package. Then run `emerge -av
--depclean` and you are done.
You could continue to remove config files but that is usually not worth
the trouble.
Hope this helps,

Also, follow the advice on the screen when you run 'emerge --depclean -p'

which is to run revdep-rebuild afterward to rebuild any dependencies. Such
dependencies may have been broken from uninstalling packages with depclean,
(man revdep-rebuild gives you more information).

The --depclean option will remove any packages that are not in
/var/lib/portage/world and are not dependencies of other installed packages
already in /var/lib/portage/world.

should not use --unmerge because it doesn't check dependencies before
removing the package.
If you want to delete a package only if no other package depends on it,
either remove it from world or use
`emerge -av --depclean <package_name>`.
The latter has the advantage of also telling you what depends on it.

But it seems that the --depclean is a dangerous operate ??

use the -a or -p option and check that it is not removing something I
want or need before letting it complete the removal. I prefer the -a
option since it is faster. If the list is correct, just hit "y" and let
it remove the unwanted packages.

packages when portage /thinks/ it is safe. unmerge will always remove
them, even if it breaks the system. Nevertheless, like Dale said, you
should be careful with depclean and use -a or -p with it. But if
depclean makes an error, there is usually something else wrong with your
system.

It is, but far less dangerous than --unmerge. depclean will only remove
packages when portage /thinks/ it is safe. unmerge will always remove
them, even if it breaks the system. Nevertheless, like Dale said, you
should be careful with depclean and use -a or -p with it. But if
depclean makes an error, there is usually something else wrong with your
system.

not dangerous. only you need to look carefully at
what depclean wants to delete.
as gentoo says, in some cases it could break
dependencies needed by other software and
to avoid damage you should run revdep-rebuild,
which scans all dependecies and reinstalls
them if it finds something is missing.
I use both regularly, especially after an emerge
--update world and never had any real
trouble with it.
hope this eases your concerns a bit

I've built a script called "autodepclean" that runs "--pretend --depclean"
and filters the output to a separate script file "cleanscript". You can
run "autodepclean" as a regular user, but "cleanscript" has to be run as
root. Here is how I use it...
1) Run autodepclean. It takes approximately 30 seconds on my machine.
2) Look at cleanscript with a text-editor, and delete lines that remove
programs you want to keep.
3) Run "cleanscript" as root. It automatically runs "revdep-rebuild" at
the end.
Note that "nano" is no longer a system requirement. If you want the
"nano" editor, you need to include it in world. I.e. "emerge nano".
The "autodepclean" script is attached to this post.
