Auto login, KUbuntu 14.10 KDE 5 plasma

Hi,

I've been trying to auto login, Kubuntu 14.10 KDE 5 plasma. I had this working by adding sddm.conf file in the etc dir containing:

[Autologin]
User=$USERNAME
Session=plasma.desktop

Substitute your user name for $USERNAME

Well, this "was"working fine. I've been doing regular

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

While keeping an eye on sddm.conf file....its still there contents unchanged, however, no more auto login!

any suggestions?

Thanks AJ
