External Monitor and Monitor of Laptop

[HyperCube]

Hello,

I just installed the the new F15 on my Laptop.

My Laptop has one onBoard Graphic: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller
and additionally the nVidia Corporation GT218 [GeForce G210M].

I connected an external AOC 22'' HD-LED Monitor with my laptop using the HDMI port and installed the NVIDIA driver.

Unfortunately, based on my current xorg.conf file only my EXTERNAL monitor works on F15 and not my laptop monitor. I am quite a noob in Linux and don't know what I have to change in my xorg.conf to work with both monitors.

Before installing the nvidia driver I could use both monitors! (however, the external one only with VGA)

My xorg.xonf
