I tried the current daily live version, during booting, the ubuntu splash
screen was at the external screen and the terminal output at the notebook.

ubuntu@ubuntu:~$ xrandr --output HDMI-1-1 --mode "1920x1080"
After that, the external screen was also shown at the internal.
There are some display failures like this and the fps seems slow, maybe 1 or 2
fps.
