I just did a fresh install of PCLOS using the recent KDE 2012.12.iso. This particular PC has been running a little quirky ever since the KDE upgrade a while back. The new installation is now running great -- it's got that new car smell and feel.
Anyway, I've always excluded "root" from the login screen, so I went to my desktop settings to do that again and realized, I have no idea what to do with all those other "Users."
What are all those user entries like "@audio", "@cdwriter" and, for that matter, "@root" and "@users"?
Should I exclude these "users" also? Or doesn't it matter?
