I managed to compile the complete CyanogenMod 11.
Then I took the kernel from gsstudios
and compiled it with the required namespaces support.

I connected to the the smartphone via adb (Android Debug Bridge).
LXC works. I started the Plasma Mobile container.
Now I can login to the ubuntu system.

Following the instructions of:
https://community.kde.org/Plasma/Mobile/CyanogenModBase
I started udev and lightdm.

The problem is that I cannot see the graphical user interface.
Can anybody help me?

Do I need special drivers in the ubuntu system for my smartphone?
