Problem after installing kubuntu-desktop from Ubuntu 15.04

[apswartz]

I installed Ubuntu 15.04 on my laptop using a new hard drive (no previous installation of any kind).
Then I used aptitude to install lubuntu-desktop and kubuntu-desktop.

First, I had all sorts of problems with a conflict between LightDM and sddm. The only way I could stop that was to make sddm the manager.

The other problem is this: Kubuntu doesn't show up as a session option. I get to choose from Ubuntu and Lubuntu, no Kubuntu.

I tried uninstalling kubuntu-desktop and re-installing it. I tried both LightDM and sddm, but Kubuntu is not an option anywhere. (Oh, yes, still had the same conflict between LightDM and sddm until I selected sddm to be the manager).

Will I need to manually enter the Kubuntu option, and, if so, how do I do that?

Thanks.

There is no "plasma" option?
Make sure plasma-workspace is installed, this package contains the xsession file for a plasma desktop login.

Doh! Yes, it is there. I was expecting KDE or something similar. Thanks.
