Als neuen Versuch, openGL zum laufen zu bringen, wird nun nvidia-PRIME installiert nach der Anleitung auf http://wiki.ubuntuusers.de/Hybrid-Grafikkarten/PRIME#PRIME-und-der-proprietaere-Nvidia-Treiber-nvidia-prime

sudo apt-get install nvidia-prime  nvidia-319-updates mesa-utils
sudo dpkg-reconfigure lightdm

Hierbei kam es dann zu der evt. interessanten Fehlermeldung:

karl@lenovo-w520:~$ sudo dpkg-reconfigure lightdm
