Startup Genymotion from CLI, resize and move it

Finally fixed the graphics (another story) and Genymotion working once again.

Following the VirtualBox Help file example meant a borked Nautilus and other networking things dying, plus I had no two way connectivity and a lost connection for my host machine. Continue reading
