New user here moving from Debian/Gnome+KDE to openSUSE+KDE desktop. I'm installing openSUSE on a new partition but keeping Debian on a separate partition for times when I need it. Both openSUSE and Debian will use the same /home that is on a separate disk.

I cannot do a completely clean install of openSUSE+KDE because KDE seems to detect a previous installation and uses these settings files. I've renamed some of the settings directories in an attempt to force the creation of new ones. For example,

mv ~/.kde ~/.kde_old
mv ~/.config/akonadi ~/.config/akonadi_old

... but this feels like a game of Whack-a-mole. If I miss a single setting file location, I end up with a non-clean install.

Can you suggest a way that I can keep my existing /home (and personal files therein) but also do a completely clean installation of openSUSE + KDE that is not contaminated by previous KDE settings files in /home or elsewhere.

Thanks for your help.
