Re: Dual-head and separated screens (:0.0/:0.1)
I have a few questions:
0) Why are you using the ConnectedMonitor option? Currently the nvidia driver will always treat a CRT as the primary display device. You cannot change this behavior with the ConnectedMonitor option.
1) What kind of a system/motherboard are you using and which BIOS version?
2) Is there a reason why you are trying to start up each X screen individually? If you just run 'startx' with no other options, what result do you get (once you've removed ConnectedMonitor from your xorg.conf)?
