[Marcin Sągol <1428328@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

Kubuntu 15.04 will use sddm as a default  login manager. If we try to
install nvidia drivers with nvidia-prime, the second will want to
install lightdm as it depends of it. Whats more lightdm will want to
install a lot of other packages.

What we need: nvidia-prime to support sddm

1. #lsb_release -rd
Description:    Ubuntu Vivid Vervet (development branch)
Release:        15.04

2. #apt-cache policy nvidia-prime
nvidia-prime:
  Installed: (none)
  Candidate: 0.7
  Version table:
     0.7 0
        500 http://archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages

3. What you expected to happen ?

nvidia-prime should work with sddm and do not require lightdm and all
its dependencies (unity packges)

4. What happened instead ?

nvidia-prime wants to install lightdm as a dependency and a lot of other
packages:

#sudo apt-get install nvidia-prime
