I have a PC that has an integrated graphics chip on the motherboard. It runs X nicely. I bought a video card (NVIDIA GEFORCE FX5200), installed it in a PCI slot, downloaded the drivers from the nvidia website, installed them, rebooted, connected the monitor to the new video card, and that worked fine.
Now I would like to run in Dual-Head mode where the integrated video chip and the new video card each drive a different monitor. I was hoping to configure that simply by running "system-config-display" (SCD) (as root) and selecting dual-head mode, but that didn't work: SCD would not save the configuration and exit, which is what normally happens when you click "ok".
What do I have to do to enable dual-head mode? Or is this not possible since I have a combo video card and integrated graphics chip system?
ps. I also posted this under "General Support" yesterday but there were no responses so I cross-posted it here since it's a new hardware installation.
