Default starting X with no monitor attached

I have a question, and I have searched everywhere and I can't find the answers. I have a setup where I need to run an X session with no physical monitor attached. The was great under the old drivers, 180.51, but the newest drivers, 195.36.15, X will not start unless a monitor is Physically plugged in. Is this a bug or a design "feature" ?

Default Re: starting X with no monitor attached

The driver features a "No scanout" mode for Quadro and Tesla cards. The driver will use it automatically for Tesla cards, but for Quadro you need to configure it by adding Option "UseDisplayDevice" "none" to your X configuration.

For GeForce GPUs, the driver requires an output. Recent drivers will fail to start if they detect no attached monitors because that's usually the result of a mistake. If you really want to force the X server to start even though no monitors are attached, you'll need to configure it to pretend one is attached anyway using the ConnectedMonitor option.
