Easiest way to remove KDE

I added KDE to my system a while back and played around with it, but I've moved on to XFCE for my needs. Trouble is, with my most recent sync, it wants to upgrade KDE. Since I no longer use it, what's the easiest way of removing all the KDE libraries from my system? I suspect I'll just have to remove them all one by one, but is there an easier way?

Find whatever kde packages you have in your world file (grep kde /var/lib/portage/world), then remove all these by hand (it shouldn't be that many).

Then `emerge --depclean` should take care of all the libraries and such.

Make sure to run --depclean with --pretend first, to make sure it doesn't remove something you want/need, and you should lso make sure your system is completely up to date before running it, especially in relation to USE flags.

`emerge -puDN` world will tell you wether you are or not.

Depends on how you installed it. Did you install kde, kde-meta, kdebase, kdebase-meta? In general, if you install a package with

KDE is a metapackage, without real content. It is used to install a collection of packages. Therefore this collection won't be unmerged when unmerging the KDE meta package. As posted before, you will find a hint in the portage introduction. Unmerge KDE, followed by:

All these process want me to upgrade KDE before de-installing it, which is what I wanted to avoid. Still I suppose I had nothing better to do on a Sunday afternoon.

If the dependency tree isn't fully up-to-date, sometimes "emerge --depclean" will attempt to remove more than it should. That's why people are recommending an "emerge --update" before the "emerge --depclean". To prevent KDE from updating, mask the new version. To do this easily, first pipe the output of "emerge -uDNpq world" into a file and then edit that file down to the list of KDE-relating things that are trying to be updated, containing only "=category/package-version", one per line, and then add that file to your "/etc/portage/package.mask" file. For instance, my current emerge run (not KDE related) resulted in the following output

Hmm, I understand your problem. I don't know if there is a solution avoiding updating the whole collection of packages before unmerging. I think it is necessary to ensure consistency. It could easily be other packages need something from the KDE dependencies, therefore they must not be unmerged.
