[edit] TwinView

TwinView is Nvidia's dual monitor feature.

The following configuration uses the Nvidia GeForce Go 7400 card using the nvidia driver. 

x11-drivers/nvidia-drivers-1.0.8776-r1

I have configured my laptop for two layouts:

  • Docking station with two DFP monitors ("Work")
  • One DFP monitor connected to laptop's VGA port ("Home")

  EndSection

In order to switch layouts you will want to (un)comment the respective lines under the "ServerFlags" section.

Note: The /var/log/Xorg* file will tell you which monitor is CRT-0 or DFP-0 or DFP-1 - search for "Connected display device(s) on GeForce Go 7400 at PCI:1:0:0:"
