Moving from KDE4 to XCFE4

Hi,
I originally installed KDE4 on my system but it was too slow to be comfortable, so I've got XFCE4 installed now and really like it. I'd like to now remove the kde parts of my system, but keep qt, as I prefer to program using it. How would I go about doing this.

Thanks.
James

Don't do it yet if you don't need the diskspace. I went back to KDE after a few months of XFCE.

Go over /var/lib/portage/world, delete everything you do not need, run emerge -a --depclean.

Generally, everyone has the right to have an opinion. However, IMHO it is not proper to be the first to reply and make a non-support post. This disqualifies the thread as "unanswered" and reduces exposure, that's a disservice.

Yeah, I didn't find it overly helpful. I'm really liking xfce. It works really well on my four year old laptop, which is the main thing. Still I'd like to clean everything up with something like a
emerge -C kde-base/* but could someone suggest the proper way to do this?

Thanks very much, and KDE users, don't take this the wrong way, I'll still code in QT, just don't have the hardware!

What I do when I've switched my DE or WM and decide to get rid of the old one is read through /var/lib/portage/world and unmerge the packages related to my old WM/DE. Then I run emerge -p --depclean, removing the -p switch when I'm satisfied I won't lose something important. If something comes up I don't want unmerged, I just run emerge --noreplace (package) on that package.

If you want to keep qt, well, you probably have the use flags in place for it already. Just leave those use flags there and qt should stick around on its own.

emerge -C kdebase-meta or emerge -C kde-meta followed by depclean should do it depending on which one you installed. Any apps that need qt should still pull it. It would also be a good idea to look through your world file and emerge -C any kde programs you installed followed by depclean. As Jaglover stated your world file is located at /var/lib/portage/world.

As it has been said above, manually deleting unnecessary applications from /var/lib/portage/world followed by emerge --depclean -a is probably the most sure way.

I also added -kde in /etc/make.conf in the USE settings. I also had default/linux/amd64/10.0/desktop/kde set as my default profile. Changed it to default/linux/amd64/10.0/desktop when I moved over to xfce.

After you think you have all the kde cleaned out, run;

If you come across any programs that you want to keep (k3b, Rosegarden, and such) that require the +kde use flag, take the use flag out of make.conf and put it in /etc/portage/package.use.

When I uninstall KDE I usually first change my profile (which you've already done). I then open my world file, go through it line by line, and emerge -C any KDE packages there. Then a simple emerge -DavuN world followed by emerge --depclean should clean things out.

If you aren't going to be using any KDE applications, a good way to tell if you've completely removed KDE or not is to see if any packages are still pulling in kde-base/kdelibs as a dependency after emerge --depclean. If it's still installed, do
