I'm a long time user of Debian/Ubuntu, but since I've retired, I'm learning other distros, and Funtoo seemed like a good choice to start with..

Since I'm a KDE user, I wanted to install KDE on the Funtoo VM, and proceeded to add KDE as a mix-in. A "epro show" shows I have "workstation (from desktop flavor)" and the "Enabled Profiles" show KDE as a mix-in.. After doing this, I did an "emerge --sync" then
