As the subject says, I can't seem to install TDE on Ubuntu 12.04. One of the last messages while installing is this:
"Setting up kde-guidance-trinity (4:3.5.13-1ubuntu0+ax0~precise) ...

The disable|enable API is not stable and might change in the future."

During install I chose kdm over lightdm. I can login ok, but I still get the Unity desktop. What can I do to rectify this?

Thanks for any hints, Mike
