Dual head on Nvidia under linux
After getting a projector I wanted to use my HTPC on both the TV and the projector at the same time with the same picture. When I only play music I don’t want to use the projector. But when I play movies…well you know.
(I have a Nvidia graphicscard)
To set up X to display both on TV-out and DFP (DVI) in clone mode:
Section “Device”

Driver “nvidia”
VideoRam 65536
